Cunning is kind of OP, it serves 2 purposes at once. It can be cheap upgrade removal AND control. It makes sense how it works but a 2 resource cost for this card is way too low. For what it does it should be 4 or 5 or be limited on what it works on like upgrades only. This card is silly open ended and cheap.
I just would hate to witness some terrible interactions being possible as more cards become available. Difficult to see, always emotion is the future.
