Be Patient, then Dash!

At a PPTQ you’re head judging, Art attacks Nin with a Dashed Lightning Berserker. The players calculate damage, then Art passes the turn. Nin takes her turn, then passes back the turn. Art attacks with the Berserker again on his next turn, pumping it multiple times with its activated ability. With the last of those activations on the stack, Nin calls you over and points out that the Berserker should have been returned to Art’s hand at the end of his last turn.

When you investigate further, you learn that Art had completely forgotten that he dashed this Berserker in since he cast one normally earlier in the game. You also learn that Nin noticed the issue during her turn, but decided to wait to call you until now to throw off Art’s game plan. What do you do?

Judges, feel free to discuss this scenario on Judge Apps!

Answer
Nin, while she noticed an infraction but didn’t call immediate attention to it, has not committed any infraction herself because players are NEVER obligated to point out their opponent’s missed triggers. Therefore she is within her right to notice the error and wait to call a judge later. She is gaining an advantage through paying more attention to the game than her opponent and knowing very well how the rules apply to the situation, both of which are legal and encouraged.

Art is guilty of GPE-Missed Trigger, and because the dash ability’s delayed trigger is generally detrimental, he will be awarded a warning. Because this is a delayed trigger that changes the zones of an object, it doesn’t expire, and will be resolved either the next time a player would get priority or at the start of the next phase, whichever Nin chooses.
