Hey all!
I would like to hear your opinions on a situation that happened during the Standard Game Day last weekend. Anton controls
Catacomb Sifter and 2 Eldrazi Scion tokens. In Nolan's turn, Nolan casts a board wipe, destroying all Anton's creatures. Nolan is now tapped out and passes the turn.
Anton untaps, draws a card, casts and resolves
Transgress the Mind, then realizes that he forgot his triggers from the Sifter. Anton calls the judge and asks if he can still add those triggers to the stack now. Would you allow that or not, and most importantly, why (not)?
Relevant section from the JAR:
A player forgets a triggered ability (one that uses the words “when,” “whenever,” or “at the beginning”, usually at the start of the ability's text)
These abilities are considered missed if the player did not acknowledge the ability in any way at the point that it required choices or had a visible in-game effect. If the ability includes the word “may,” assume the player chose not to perform it. Otherwise, use your judgement to decide if putting the trigger on the stack now would be too disruptive - don’t add it to the stack if significant decisions have been made based on the effect not happening! Unlike other illegal actions (which must be pointed out), players may choose whether or not to point out their opponent's missed triggers, though we should encourage them to do so.
