Request changes — this parser fix is in a path that production bypasses.
🔴 Blocker
[HIGH] The list grammar is only wired into the generic object-hosted replacement parser. Evidence: crates/engine/src/parser/oracle_effect/mod.rs:5212-5227 detects Whenever you cast … enters with … and calls the dedicated parse_whenever_you_cast_enters_with_trigger; its parser at crates/engine/src/parser/oracle_replacement.rs:4912-5000 consumes exactly one +1/+1/-1/-1 counter, while this PR changes only parse_replacement_line_ir at oracle_replacement.rs:4061-4072. Why it matters: the actual trigger path therefore rejects or truncates the counter lists this PR claims to support. Suggested fix: extract/reuse the counter-entry list grammar from the dedicated trigger parser, then build every PutCounter payload there.
[HIGH] The added parser tests do not prove the production trigger pipeline or malformed-input behavior. Evidence: the dedicated trigger path above is selected before the generic replacement path; the negative test proceeds when parsing returns None. Why it matters: such tests can pass while March Toward Perfection, Arcane Archery, and Tenacious Pup still do not produce the intended trigger/engine behavior. Suggested fix: add production trigger-AST and runtime regressions for all three cards, including an assertion that the parser reaches the intended trigger rather than accepting None.
Recommendation: request changes. Please generalize the counter-list grammar at the trigger parser’s actual authority and cover the real trigger/runtime path before this is reconsidered.
Parse diff came back empty — the review's conclusion is correctCI posted Where I differ is the mechanism, and it changes what the fix should be. It isn't the trigger path — the boon wrapper is never strippedRunning all three cards end-to-end on this branch:
There is no boon handling anywhere in the parser ( So the counter-list grammar is never reached with clean input for any of the three. Wiring it into the trigger parser would not fix them either.

Request changes — the current refactor still leaves the production cast-enters authority on a separate single-counter grammar, and its tests do not reach that authority.
🔴 Blocker
[HIGH] The generic replacement change is not wired through the cast-enters dispatcher. Evidence: crates/engine/src/parser/oracle.rs:5217-5229 routes a matching Whenever you cast … enters with … line to parse_whenever_you_cast_enters_with_trigger, whose payload parser at crates/engine/src/parser/oracle_replacement.rs:4912-5000 still accepts exactly one +1/+1 or -1/-1 counter. This PR changes the generic replacement reader at oracle_replacement.rs:4061-4072. Why it matters: a real cast-enters line bypasses the new list grammar, so the duplicated production authority cannot implement or prove conjoined/elided counters. Suggested fix: factor the shared counted/elided entry-list grammar at the trigger authority (while preserving its dynamic-count semantics), construct every PutCounter payload from that list, and retain strict failure for unsupported suffixes.
[HIGH] The added parser tests bypass the selected production trigger path, and the negative guard is vacuous when the parser returns None. Evidence: production dispatch selects parse_whenever_you_cast_enters_with_trigger before the generic replacement path (oracle.rs:5226-5229); the PR's direct parse_replacement_line/entry-reader tests therefore do not establish trigger AST or runtime behavior. Why it matters: passing unit tests can coexist with a trigger that neither parses nor installs every counter replacement. Suggested fix: add a production trigger-AST assertion and a scenario/runtime assertion that fail on reverting the production list wiring, plus a positive reach guard before every malformed-input negative assertion.
The contributor correctly identified that March Toward Perfection, Arcane Archery, and Tenacious Pup are additionally blocked upstream by their quoted-boon wrapper; that does not remove the independent duplicated cast-enters authority above. The parse-diff sticky is still bound to old head f53e6d42054d1b0348f8d7acd0abd2e8a58b483d, and the CI run for this head is queued, so neither is current-head evidence.
Recommendation: request changes. Generalize at the production trigger authority and demonstrate the end-to-end trigger behavior; keep the boon-wrapper repair separately scoped.

…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.

Required: carry elided counter lists through comma separators
At dfa79c4e83cd5b4387e8510b468825136b22d20f, crates/engine/src/parser/oracle_effect/lower.rs:11084-11090 grows the new elided-count tail with only tag(" and "). The same shared suffix reader is used by the imperative path at crates/engine/src/parser/oracle_effect/imperative.rs:9050; a comma/Oxford-comma list such as with an additional +1/+1 counter, reach counter, and trample counter on it therefore stops after the first counter instead of lifting all singular elided riders. The replacement-side reader already recognizes ", " and ", and " (crates/engine/src/parser/oracle_replacement.rs:4802-4806), so this is an unhandled sibling grammar rather than a deliberate syntax boundary.
Please use a composed separator combinator covering ", ", ", and ", and " and " at this reader as well, and add a discriminating comma/Oxford-comma elided-count parser regression. The production cast-enters authority and its reach-guard test now satisfy the prior request; this is the remaining current-head blocker.

Request changes — the new shared counter-list route can publish a partial triggered ability.
🔴 Blocker
[MED] A fixed conjoined counter list is accepted without preserving or validating the text after on it. Evidence: crates/engine/src/parser/oracle_replacement.rs:5028-5039 returns a complete ChangeZone replacement immediately after parse_enters_counter_entries(rest), while parse_enters_counter_entries at :4772-4794 consumes only through on it and returns no remainder. Why it matters: a line such as Whenever you cast a creature spell, that creature enters with an additional +1/+1 counter and deathtouch counter on it and with haste now installs counters but silently drops the haste rider; that falsely treats a rules-bearing full sentence as supported. Suggested fix: have the shared-list route return/validate its suffix and either compose a supported rider or fail closed before constructing AddTargetReplacement; add a production-entry regression for the trailing-rider case.
The exact-head parse receipt reports no current card-parse change and required CI is green, but neither addresses this semantic partial-parse path.
Recommendation: preserve or fail closed on the remaining rider, then request a fresh current-head review.

Request changes — the new trigger-level fail-closed guard still falls through to an object-hosted replacement in the production dispatcher.
🔴 Blocker
[HIGH] The production route does not fail closed on the trailing rider. Evidence: crates/engine/src/parser/oracle.rs:5271-5283 calls the dedicated cast-enters recognizer and, when it returns None, immediately passes the same Whenever you cast … line to parse_replacement_line_ir; that replacement dispatcher’s broad enters/counter route at crates/engine/src/parser/oracle_replacement.rs:721-728 accepts it through parse_enters_with_counters. The new test at oracle_replacement.rs:21657-21670 only asserts the dedicated recognizer is None, so it does not reach this fallback. Why it matters: Whenever you cast a creature spell, that creature enters with an additional +1/+1 counter and deathtouch counter on it and with haste is still published as an object-hosted counter replacement and silently loses the haste rider; it also changes the cast-trigger lifetime/authority the parser’s own oracle_replacement.rs:703-713 comment says must not be modeled there. Suggested fix: make the Priority 5-pre dispatcher preserve the dedicated trigger authority for this recognized cast-enters shape when its full clause is unsupported—emit the existing strict/unimplemented path or otherwise prevent the generic replacement fallback—and add a parse_oracle_text regression for the rider case that proves no partial replacement is emitted, paired with the rider-free positive production-path case.
Recommendation: request changes. The current head needs an end-to-end fail-closed boundary before the counter-list support can be approved.

Approved at fd644b511a5b287684671c7d2e85c1699c60d6ce: the cast-enters outcome now distinguishes an unsupported recognized shape from a non-match, emits an explicit residual rather than falling through, and has paired production-path regressions. Required CI is green and the current parse-diff receipt reports no card-parse changes.
Rebased onto current main and reworked to address the review on #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.
parse_whenever_you_cast_enters_withparsed exactly one +1/+1 or -1/-1 counterof 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_entriesfirst and keeps itsbespoke parse only as the fallback.
The list route is gated on every count being
Fixed, which is what keeps the twocount 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_dynamicpins it.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_elementserves both readers; its two guards(recognized-type-only via
parse_strict_counter_type, singular noun) replace theleading number that anchors the counted form.
Corrects the doc comment on
parse_enter_counters_clause_body, which iswrong 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_listgoes through
parse_whenever_you_cast_enters_with_trigger-- the real entrypoint -- 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 122.1tags added to pure grammar are removed: 122.1defines 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 fix(parser): lift the "and with <keyword>" entry rider on the kicker cycle #7768
and tracked by Kicker cycle: "enters with ... and with <ability>" silently drops the granted ability (9 cards) #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 fix(parser): lift the "and with <keyword>" entry rider on the kicker cycle #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 (#7495), which
feeds the whole boon sentence to the counter grammar.
