How does Spectral Matron work when?

Question

Accepted Answer

When you play Spectral Matron, its “When you play me…” ability is a triggered ability created by playing the card. That trigger may be placed on the chain during finalization; if you choose to finalize it you pick a qualifying unit card in your trash (cost ≤ 3 energy and ≤ rainbow runes) and the ability becomes the chain item that will cause you to play that chosen unit while ignoring its cost. Cleanups and timing rules in the FEPR/finalization process apply as described below.

Play Spectral Matron normally. Its “When you play me, you may play a unit costing no more than :rb_energy_3: and no more than :rb_rune_rainbow: from your trash, ignoring its cost.” is a triggered ability that is offered to be placed on the chain when you play the card [333]. During finalization you may choose to put that trigger on the chain and choose a legal unit in your trash that meets the restrictions; once finalized, the effect on the chain will be the instruction to play that specific unit from your trash ignoring its cost (the choice of which unit is made during finalization) [FAQ:unleashed#1] [FAQ:unleashed#2] [333]. If there is no legal unit to choose during finalization, you cannot finalize that trigger and it will not become a finalized chain item [FAQ:unleashed#2]. After Pending/Legal items are added or finalized, Cleanups may become outstanding per the Cleanup rules [319.3] [319.4]; Cleanups will not interrupt the steps of finalization itself [FAQ:unleashed#17].

You play Spectral Matron. Because a card was played, a Chain is created [333]. The text “When you play me, you may …” is a triggered ability tied to that play. The ability will be offered to be added to the chain as a Pending Item (the “you may” is the decision to place it there) and will be queued for finalization per the triggered-ability structure explained in the FAQs [FAQ:unleashed#1] [FAQ:unleashed#2]. During finalization you choose whether to place the trigger on the chain. If you choose to place it, you must choose a legal unit card in your trash that meets the restrictions (cost ≤ :rb_energy_3: and ≤ :rb_rune_rainbow:) as part of finalization; if no legal choice exists you cannot finalize the effect into a finalized chain item [FAQ:unleashed#2]. Once finalized, the effect on the chain will be the instruction to play that specific chosen unit from your trash while ignoring its cost. After items are added or finalized, Cleanups become Outstanding as appropriate (for example, after a Pending Item is added or becomes Legal) [319.3] [319.4] but Cleanups do not interrupt the act of finalization itself [FAQ:unleashed#17]. When the chain item (the Matron-trigger effect) resolves, you perform the instruction: play the chosen unit from your trash, ignoring its cost. Normal timing/legal-timing rules apply for playing a card (cards are normally played only when you have priority in a Neutral Open state and Showdown timing rules if relevant) [310.1.a] [347.1.a].

If there is no legal unit in your trash that meets the “≤ :rb_energy_3: and ≤ :rb_rune_rainbow:” restrictions at finalization, you cannot finalize the triggered ability and it will not become a finalized chain item to resolve [FAQ:unleashed#2]. If the chosen unit is removed from your trash between the time you place the trigger as Pending and the time you finalize it such that there is no legal target during finalization, the trigger cannot be finalized (you can’t choose an illegal target) [FAQ:unleashed#2]. “Ignoring its cost” is taken to mean you don’t pay the unit’s printed cost when playing it; the provided rules text does not further define every implication, so if a unit has an additional cost-within-instruction or unique play restriction that is not literally its printed cost, the supplied Core Rules context does not definitively state whether those are ignored — see assumptions. If the environment/timing at resolution forbids playing cards (for example, some Showdown/phase restrictions), the Matron-trigger’s finalized play instruction is still the chain item to resolve but whether it can produce a legal play may depend on timing/legality assessed during finalization and execution per the FEPR process [FAQ:unleashed#17] [310.1.a].

Short answer: Playing Spectral Matron creates a triggered ability "When you play me…" that you may place on the chain; during finalization you choose a legal unit in your trash that costs no more than :rb_energy_3: and no more than :rb_rune_rainbow:, and the triggered ability becomes the chain item that tells the game to play that chosen unit ignoring its cost. Explanation and evidence from the rules: When you play a card, a chain is created [333], and the player who created that chain gains first priority [333.1]. Triggered abilities such as “When you play me…” follow the split structure described in the FAQs: there is the trigger and the “you may,” and the effect (the instruction to play the unit) only becomes a finalized chain item if the controller places the ability on the chain and chooses a legal target during finalization [FAQ:unleashed#1] [FAQ:unleashed#2]. After pending items are added or become legal items, Cleanups can become outstanding [319.3] [319.4]; however, Cleanups do not happen during finalization itself, they only occur between FEPR steps, so finalization of the Matron-trigger is not interrupted by a cleanup in mid-finalize [FAQ:unleashed#17]. Once the Matron-trigger resolves it performs its effect: you play the selected unit from your trash ignoring its cost (the exact wording on the card). Note that "ignoring its cost" prevents you from paying the unit's printed cost, but the provided rules context does not exhaustively define whether it overrides every possible cost-like requirement printed on a unit; I treated it as not paying the printed cost but not as a blanket override of other textual constraints unless those are explicitly part of the phrase. Finally, remember that play/activation timing rules still govern whether a card can be played in a given state (cards are normally played when a player has priority in Neutral Open; during Showdown the Focus/Showdown rules apply) [310.1.a] [347.1.a].
