The way to stop the card is give your opponent cash and cake Mmm cake. Actually you can just use Anesthetizng Opulence to destroy the creature and let your opponent draw a card; hope he doesn't draw a creature. That will stop the craghammer. Or you can just activate Bomb Threat and make the game a draw. Hey man you at least get to see the Police and the bomb squad. Actually this card is not real and there isn't a way you can draft it.
