📝 WalkthroughWalkthroughChangesThe enters-with-counters parser now preserves supported Kicker keyword rider parsing
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change grants bare keyword riders on kicked creatures, but chained "and with" riders could still cause the first keyword to be omitted, leaving affected cards with incomplete rules behavior. The risk is limited to that specific card-text shape and should have explicit owner follow-up. Sequence Diagram(s)sequenceDiagram

…cycle Refs phase-rs#7721 -- PARTIAL, deliberately not an auto-closing trailer. This fixes the bare-keyword rider: 10 of the 13 printed lines, and 6 of the 9 cards outright. The quoted-ability rider scoped out below leaves Anavolver, Necravolver and Rakavolver each still missing one half, so the issue must stay open. CR 614.1c makes "If this creature was kicked, it enters with three +1/+1 counters on it and with trample" ONE replacement effect. Only the counters were being read. `parse_enters_with_counters` composes exactly one sibling entry rider -- `has_enters_tapped_phrase` -- and there was no extractor for the keyword clause, so nine cards entered with their counters and silently without their granted ability: Anavolver, Cetavolver, Faerie Squadron, Kavu Titan, Necravolver, Pouncing Kavu, Pouncing Wurm, Rakavolver, Voidpouncer. A corpus sweep over every printed "enters/enter with ... counter" and battlefield-rider line finds the rider on exactly those nine and no others. `parse_enters_with_keyword_riders` scans at " and with " boundaries rather than anchoring, because the rider trails a counter clause of unbounded shape and is not the first " and " in the line -- Voidpouncer prints a conjoined counter list ("two +1/+1 counters and a trample counter on it") before it. Each candidate remainder is offered to the shared `parse_granted_keyword_fragment`, and a candidate that is not a keyword simply does not match, which is what keeps the counter list's own conjuncts out: "a trample counter on it" is not a keyword. Pinned by `enters_with_keyword_rider_does_not_over_claim` over Dust Animus and Agent's Toolkit, whose "<keyword> counter" conjuncts must stay counters. CR 611.2a governs the grant's shape. The tapped precedent does NOT transfer: tapping happens once as the object enters, so a one-shot `SetTapState` is right there, whereas a granted keyword is a characteristic the permanent must KEEP while it remains on the battlefield -- and must lose on leaving, so the new object it becomes elsewhere does not inherit it. Modeled as a continuous `AddKeyword` on `SelfRef` with `Duration::UntilHostLeavesPlay`, composed onto the same execute chain as the counters. That reuses the definition's existing condition, so the kicker gate (CR 702.33d) applies to the grant for free rather than being re-derived. The QUOTED-ability rider in the same slot -- `and with "Whenever this creature deals damage, you gain that much life."` (Anavolver's {B} half, Necravolver's {W}, Rakavolver's {1}{W}) -- is deliberately out of scope: it needs a granted-ability parse, not a keyword lookup. Those three lines keep their current counters-only behavior rather than being failed closed, since that would trade a partial parse for no parse at all. Left on phase-rs#7721. Two existing tests had been passing green through the entire gap by asserting the counter and saying nothing about the rider (`kicked_enters_with_counter` on Ana Battlemage's flying, `kicked_with_specific_cost_enters_with_counters` on Necravolver's first strike). Both now assert the keyword grant through a shared `assert_keyword_grant` helper, so they can no longer go quiet if the rider is dropped again. Runtime coverage in `kicker_enters_with_keyword_rider.rs` pays the kicker through the real `DecideOptionalCost` flow, so the entering object's `kickers_paid` is populated authentically. Both polarities are asserted, and each pairs the keyword with a +1/+1 counter reach-guard so a spell that never resolved cannot satisfy either assertion vacuously -- an AST-only test would have proven the parse without proving the keyword ever reaches the battlefield.

|---|---|---|
| Printed lines | 10 of 13 | 3 |
| Cards | 6 of 9 outright | Anavolver, Necravolver, Rakavolver each keep one broken half |
The remaining three lines put a quoted ability in the same grammatical slot rather than a keyword:
- Anavolver
{B}—and with "Pay 3 life: Regenerate this creature." - Necravolver
{W}—and with "Whenever this creature deals damage, you gain that much life." - Rakavolver
{1}{W}— same triggered ability
Those need a granted-ability parse, not a keyword lookup, so they are deliberately out of scope. They keep their current counters-only behavior rather than being failed closed — failing closed would trade a partial parse for no parse at all, which is a coverage regression on cards that at least place their counters today.
The trailer is now Refs #7721, which links without closing. Whoever merges this should leave #7721 open; it can be closed once the quoted-ability form lands.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Fix the candidate boundary so chained "and with X and with Y" riders do not silently drop the first keyword.
parse_enters_with_keyword_riders bounds each candidate by the next . (after_marker.split('.').next()), not by the position of a following " and with " marker. For a hypothetical line with two chained riders, "... and with X and with Y.", the first candidate becomes "X and with Y". parse_granted_keyword_fragment rejects this compound string as not a bare keyword, so X is silently dropped. The loop then advances to the second " and with " and correctly captures only Y.
This does not affect the nine known corpus cards (each has exactly one rider), but the function signature (Vec<Keyword>) and the while loop are written to support multiple riders. If a future card prints two chained bare-keyword riders, this exact bug class (silent keyword drop) — the one this PR fixes — reappears here.
Bound each candidate to stop at whichever comes first: the next . or the next " and with " marker.
Based on learnings: path instructions state "A latent bug behind a guard or unreached branch is still a finding — rate it by what happens when the form is reached ... not by today's reachability."
🐛 Proposed fix to bound each candidate at the next rider marker
- let candidate = after_marker
- .split('.')
- .next()
- .unwrap_or(after_marker)
- .trim();
+ let next_marker_start = after_marker.find(" and with ");
+ let sentence_end = after_marker.find('.');
+ let candidate_end = match (next_marker_start, sentence_end) {

Required: do not truncate chained keyword riders
At d55cdb18e8e166ea644866e9680c8fc0180318a5, the new rider extraction in crates/engine/src/parser/oracle_replacement.rs:4371-4391 bounds its candidate only at .. For text shaped and with X and with Y, that lets the first bare keyword be swallowed by the candidate; only the latter rider is parsed. This is a latent parser-class regression, not just a Kavu Titan case.
Please use a composable nom boundary (or an equivalent scanner with correct rider boundaries) so every chained and with … rider is represented, and add a discriminating parser regression containing two riders. The current Kavu Titan runtime coverage is factual and should remain; it does not exercise the two-rider parser shape.

…lided counts Rebased onto current main and reworked to address the review on phase-rs#7490. The conjoined "enters with" counter grammar had THREE readers. This gives it one authority and extends that authority, rather than widening one reader in a path production does not take. 1. The cast-enters TRIGGER path now routes through the shared list reader. `parse_whenever_you_cast_enters_with` parsed exactly one +1/+1 or -1/-1 counter of its own, so any conjoined list handed to it was truncated -- and that, not the self-ETB replacement path, is the reader a "Whenever you cast ..., that creature enters with ..." line actually reaches (oracle.rs Priority 5-pre intercepts and routes there). It now tries `parse_enters_counter_entries` first and keeps its bespoke parse only as the fallback. The list route is gated on every count being `Fixed`, which is what keeps the two count axes from crossing. The shared reader rewrites a bare X to the entering object's `CostXPaid` -- correct for a self-ETB "enters with X counters" (CR 614.12), wrong here, where X is bound by the trailing "where X is ..." clause. Communal Brewing ("enters with X additional +1/+1 counters on it, where X is the number of ingredient counters on this enchantment") would silently become CostXPaid without the gate. No printed card combines a conjoined list with an X count in this position, so the gate costs no coverage. `whenever_you_cast_trigger_keeps_where_x_count_dynamic` pins it. 2. Elided-count conjuncts, as before. English coordination lets the leading determiner distribute -- "an additional [+1/+1 counter] and [deathtouch counter]" -- so a later conjunct can carry no count. Shared `parse_countless_counter_element` serves both readers; its two guards (recognized-type-only via `parse_strict_counter_type`, singular noun) replace the leading number that anchors the counted form. 3. Corrects the doc comment on `parse_enter_counters_clause_body`, which is wrong on main: it claims the self-referential seam lifts only the first conjunct and that routing it through this list is the follow-up. That seam is a CR 614.1c object-hosted replacement with its own conjoined-list reader and has always lifted every conjunct. Review asks, addressed: * Production-path tests. `whenever_you_cast_trigger_lifts_conjoined_counter_list` goes through `parse_whenever_you_cast_enters_with_trigger` -- the real entry point -- and asserts both conjuncts on the floating replacement's payload, anchored by positive reach guards (trigger is Some, mode is SpellCast, the install is the one-shot AddTargetReplacement) so it cannot pass vacuously on a parse that never arrived. * CR annotations. The `CR 122.1` tags added to pure grammar are removed: 122.1 defines what a counter IS and governs none of elision, conjunct position, or reader plumbing. The elided-count combinator now states explicitly why NO CR is cited on it, and points at CR 614.1c where the counters are actually applied. * Suffix preservation. The Voidpouncer case pins where the counter list STOPS; the trailing "and with haste" rider is dropped on this branch. That is a separate pre-existing bug covering nine Invasion kicker cards, fixed in phase-rs#7768 and tracked by phase-rs#7721. A scope note now records that in place, so the silence is deliberate rather than mistaken for correct behavior, and names the assertion to add once phase-rs#7768 lands. Still no card-parse change expected: the three cards that print an elided-count list (March Toward Perfection, Arcane Archery, Tenacious Pup) are blocked upstream by an unparsed "You get a one-time boon with ..." wrapper (phase-rs#7495), which feeds the whole boon sentence to the counter grammar.

A scope note now records that in place, so the silence is deliberate rather than mistaken for correct behavior, and names the assertion to add once phase-rs#7768 lands. Still no card-parse change expected: the three cards that print an elided-count list (March Toward Perfection, Arcane Archery, Tenacious Pup) are blocked upstream by an unparsed "You get a one-time boon with ..." wrapper (phase-rs#7495), which feeds the whole boon sentence to the counter grammar.

…lided counts Rebased onto current main and reworked to address the review on phase-rs#7490. The conjoined "enters with" counter grammar had THREE readers. This gives it one authority and extends that authority, rather than widening one reader in a path production does not take. 1. The cast-enters TRIGGER path now routes through the shared list reader. `parse_whenever_you_cast_enters_with` parsed exactly one +1/+1 or -1/-1 counter of its own, so any conjoined list handed to it was truncated -- and that, not the self-ETB replacement path, is the reader a "Whenever you cast ..., that creature enters with ..." line actually reaches (oracle.rs Priority 5-pre intercepts and routes there). It now tries `parse_enters_counter_entries` first and keeps its bespoke parse only as the fallback. The list route is gated on every count being `Fixed`, which is what keeps the two count axes from crossing. The shared reader rewrites a bare X to the entering object's `CostXPaid` -- correct for a self-ETB "enters with X counters" (CR 614.12), wrong here, where X is bound by the trailing "where X is ..." clause. Communal Brewing ("enters with X additional +1/+1 counters on it, where X is the number of ingredient counters on this enchantment") would silently become CostXPaid without the gate. No printed card combines a conjoined list with an X count in this position, so the gate costs no coverage. `whenever_you_cast_trigger_keeps_where_x_count_dynamic` pins it. 2. Elided-count conjuncts, as before. English coordination lets the leading determiner distribute -- "an additional [+1/+1 counter] and [deathtouch counter]" -- so a later conjunct can carry no count. Shared `parse_countless_counter_element` serves both readers; its two guards (recognized-type-only via `parse_strict_counter_type`, singular noun) replace the leading number that anchors the counted form. 3. Corrects the doc comment on `parse_enter_counters_clause_body`, which is wrong on main: it claims the self-referential seam lifts only the first conjunct and that routing it through this list is the follow-up. That seam is a CR 614.1c object-hosted replacement with its own conjoined-list reader and has always lifted every conjunct. Review asks, addressed: * Production-path tests. `whenever_you_cast_trigger_lifts_conjoined_counter_list` goes through `parse_whenever_you_cast_enters_with_trigger` -- the real entry point -- and asserts both conjuncts on the floating replacement's payload, anchored by positive reach guards (trigger is Some, mode is SpellCast, the install is the one-shot AddTargetReplacement) so it cannot pass vacuously on a parse that never arrived. * CR annotations. The `CR 122.1` tags added to pure grammar are removed: 122.1 defines what a counter IS and governs none of elision, conjunct position, or reader plumbing. The elided-count combinator now states explicitly why NO CR is cited on it, and points at CR 614.1c where the counters are actually applied. * Suffix preservation. The Voidpouncer case pins where the counter list STOPS; the trailing "and with haste" rider is dropped on this branch.

Refs #7721 -- PARTIAL, deliberately not an auto-closing trailer. This fixes the
bare-keyword rider: 10 of the 13 printed lines, and 6 of the 9 cards outright.
The quoted-ability rider scoped out below leaves Anavolver, Necravolver and
Rakavolver each still missing one half, so the issue must stay open.
CR 614.1c makes "If this creature was kicked, it enters with three +1/+1
counters on it and with trample" ONE replacement effect. Only the counters were
being read.
parse_enters_with_counterscomposes exactly one sibling entryrider --
has_enters_tapped_phrase-- and there was no extractor for thekeyword clause, so nine cards entered with their counters and silently without
their granted ability: Anavolver, Cetavolver, Faerie Squadron, Kavu Titan,
Necravolver, Pouncing Kavu, Pouncing Wurm, Rakavolver, Voidpouncer. A corpus
sweep over every printed "enters/enter with ... counter" and battlefield-rider
line finds the rider on exactly those nine and no others.
parse_enters_with_keyword_ridersscans at " and with " boundaries rather thananchoring, because the rider trails a counter clause of unbounded shape and is
not the first " and " in the line -- Voidpouncer prints a conjoined counter list
("two +1/+1 counters and a trample counter on it") before it. Each candidate
remainder is offered to the shared
parse_granted_keyword_fragment, and acandidate that is not a keyword simply does not match, which is what keeps the
counter list's own conjuncts out: "a trample counter on it" is not a keyword.
Pinned by
enters_with_keyword_rider_does_not_over_claimover Dust Animus andAgent's Toolkit, whose " counter" conjuncts must stay counters.
CR 611.2a governs the grant's shape. The tapped precedent does NOT transfer:
tapping happens once as the object enters, so a one-shot
SetTapStateis rightthere, whereas a granted keyword is a characteristic the permanent must KEEP
while it remains on the battlefield -- and must lose on leaving, so the new
object it becomes elsewhere does not inherit it. Modeled as a continuous
AddKeywordonSelfRefwithDuration::UntilHostLeavesPlay, composed ontothe same execute chain as the counters. That reuses the definition's existing
condition, so the kicker gate (CR 702.33d) applies to the grant for free rather
than being re-derived.
The QUOTED-ability rider in the same slot --
and with "Whenever this creature deals damage, you gain that much life."(Anavolver's {B} half, Necravolver's{W}, Rakavolver's {1}{W}) -- is deliberately out of scope: it needs a
granted-ability parse, not a keyword lookup. Those three lines keep their
current counters-only behavior rather than being failed closed, since that would
trade a partial parse for no parse at all. Left on #7721.
Two existing tests had been passing green through the entire gap by asserting
the counter and saying nothing about the rider (
kicked_enters_with_counteronAna Battlemage's flying,
kicked_with_specific_cost_enters_with_countersonNecravolver's first strike). Both now assert the keyword grant through a shared
assert_keyword_granthelper, so they can no longer go quiet if the rider isdropped again.
Runtime coverage in
kicker_enters_with_keyword_rider.rspays the kickerthrough the real
DecideOptionalCostflow, so the entering object'skickers_paidis populated authentically. Both polarities are asserted, andeach pairs the keyword with a +1/+1 counter reach-guard so a spell that never
resolved cannot satisfy either assertion vacuously -- an AST-only test would
have proven the parse without proving the keyword ever reaches the battlefield.
