Destroy an enemy minion.
This is obviously good, and makes me think they're very likely going to rotate sap.Assassinate was already a pretty good card, held back mostly by the class it's in and just being a *little* too slow to be playable.

Walk the plank just got powercreeped by a basic card.
Good luck trying to kill your own sylvanas with the basic card kappa
