It will lose it's strength rather quickly as a trick, though, because as the attack gets higher you get less extra attacks, and those hit for relatively little. Still free damage though.
And I am pretty sure, while this isn't a bug, it does work. Will be even more interesting post-update on patience.
Related question: 3/3 adrenaline frog. Play patience. Does he get +1 before or after adrenaline triggers? After means he attacks four times, first stopped by delay. Before means he only attacks three times, one still being stopped.
Logic tells me it applies it before, so that it wouldn't try to attack four times with a 4 attack creature, which it doesn't know how to do (I think).
