Should this card not have a not now/confirm choice like Days Undoing and Behold the Beyond rather than autocasting ?
The debate on whether or not cards should autocast is as old as the game. It used to be that all non-targeted spells would autocast. Now its roughly 50-50.
I personally think that all spells should have a confirmation box, but I dunno
Maybe they change it, like BfB.
+1 confirmation box wanted
Concur, anything that causes you to discard or exile cards from your hand should have a confirmation dialog.
They should have a rule for every card or an evergreen icon on card at least, that you know what happens when not disabled.
