at the recent PPTQ we faced following situation:
Andrew controls
Watchful Naga. He turns it sideways, loudly saying “EXERT!”.
Nathan, after some time passed, blocks with his 3/2 creature, asks “Damage?”
Andrew confirms and upon putting the Naga to his graveyard says: “Oh, I should have drawn a card, so I draw now?” Nathan calls for a judge.
Is it a standard Missed trigger or a GRV (because Exert and the trigger are linked) wit possible backup?
