When Viktor Innovator is played via Portal Rescue on opponent's turn, does he see himself being played and create a 1M Recruit?

Question

Accepted Answer

You cannot play Portal Rescue on an opponent's turn (its card text restricts when it can be played). Therefore the exact scenario as stated (using Portal Rescue on an opponent's turn to play Viktor - Innovator) is not legal. If, however, some other effect (one that is legal on an opponent's turn) causes you to play Viktor - Innovator to your base during your opponent’s turn, his triggered ability will see that play and you will play a 1 [M] Recruit token to your base.

No — you can't do that with Portal Rescue because Portal Rescue's text restricts when it may be played. If a unit is nevertheless played to your base on an opponent's turn by a different, legal effect, Viktor - Innovator's "When you play a card on an opponent's turn" trigger will trigger and produce a 1 [M] Recruit token.

Check whether Portal Rescue can legally be played on the opponent's turn. Its printed restriction says to play it on your turn or in showdowns only; therefore you cannot play it on an opponent's turn (scenario is illegal). If instead some other legal effect on your opponent's turn performs a 'play [card] to base' action for Viktor - Innovator, that action is a play event that occurs during your opponent's turn, fulfilling the condition "When you play a card on an opponent's turn." Refer to how triggered abilities are placed on the chain once their condition is met [FAQ:unleashed#2]. When that play event is finalized/resolved, Viktor - Innovator's triggered ability will become a pending chain item and then resolve, producing the 1 [M] Recruit token to your base as written (the Recruit token is defined by rule 184.1) [184.1]. Be mindful of replacement effects that could change the event (or the object that's played). Replacement Effects that apply to the play will alter the event and their results inherit other modifications as described in rule 370 and rule 375 [370] [375]. If the unit that was 'played' stops being the same object because it changed zones to/from a Non-Board Zone and returned, other targeting/legality consequences may apply per rule 359, but the plain 'play a card to base during opponent's turn' case will let Viktor - Innovator see the play and trigger [359].

If Portal Rescue literally cannot be played on an opponent's turn (per its text), the scenario is impossible without another effect allowing it; in that case, Viktor - Innovator will not be played by Portal Rescue on the opponent's turn and thus cannot trigger (card-play restriction prevents the whole line). If a Replacement Effect changes the 'play' into some other event (or duplicates it), that Replacement Effect applies and its replacements inherit modifications; this can change what triggers see or how many tokens are produced [370] [375]. If the object that ends up at your base is not the same object that was 'played' (because it changed Zones to or from a Non-Board Zone and returned), it may not be treated as the same object for targeting or for some triggers—consult rule 359 for objects that change zones [359]. If something 'plays' the unit but also contains additional timing text or conditional sequencing, use the triggered-ability finalization sequencing guidance from the FAQ to determine when the "When you play a card on an opponent's turn" ability is placed on the chain [FAQ:unleashed#2].

Short answer: The specific line you asked about (playing Viktor - Innovator via Portal Rescue on an opponent's turn) is not legal because Portal Rescue's printed timing limits it to "Play on your turn or in showdowns." If you cannot legally cast Portal Rescue on your opponent's turn, you cannot use it to play Viktor - Innovator during that turn, so his "When you play a card on an opponent's turn" trigger will not occur in that exact scenario. If, however, some other effect that is actually legal on an opponent's turn causes you to "play" Viktor - Innovator to your base during your opponent's turn, that is a play event that happens on your opponent's turn and will fulfill the condition of Viktor - Innovator's triggered ability. The trigger will be placed on the chain when its condition is fulfilled and will resolve to play a 1 [M] Recruit token into your base, as defined by rule 184.1 [184.1] and with replacement-effect interactions governed by rules 370 and 375 [370] [375]. Also be aware of zone-change nuances: if the unit changes zones in a way that makes it a different object by the time relevant effects check it, targeting/legality and trigger behavior can be affected per rule 359 [359]. Finally, use the FAQ guidance for how triggered abilities finalize and become chain items when their conditions are met [FAQ:unleashed#2].
