Im not really sure of what good ones there are out there...
put down any abilities/bonuses that make them your favourite!
In my opinion, graf is not that great thing!
after all Z3r0 D34d is a 7/4 with atop opp ability and Graff is only a 8/2 stop opp ability! Z3r0 D34d is should be the rare one instead of Graff!
Veenyle is a nice card, it makes the oponent spent at least one pill (if he has no stop bonus) and reduces 3 of damage, but I think Sheitane atill the 2 star card, right followed by grabielle and Flo (but more Gabrielle)
