Animal Crossing

Whenever an artifact or creature or you control
leaves the battlefield, you may search your library
for an artifact or creature card and reveal it. If
you do, you may cast that card this turn (you still
pay its costs). Otherwise, put it into your hand.
Hmm... yes. That'll cost you 3000 bells. Oh, and one
of our residents wishes to move out.... Should I let-
Oh ho ho? You will not allow them to leave under
any circumstances, eh? Duly noted! I'll guarantee it!
