Those are great DJ! I would say though that the Hamster needs to change slightly. I think it needs to be chained to the setting of one of your spell/trap cards. Then on the next turn, if that card properly negates the activation of a spell/trap/or effect, then you get to say Dun Dun DUNNNNN! Again and take 1000 from your opponent.
Isn't there a Leroy Jenkins card for WoW?
