1 Snapback

The idea, obviously, is to play as many cheap creatures, cantrips, and removal as fast as you can, and then refill your hand with Day's Undoing just like you would with the old Treasure Cruise. Yes, it's a symmetrical effect, but your opponent shouldn't be able to match your tempo.
Snapback into Undoing is just brutal. It also messes with everyone's threshold/delve.
