Spyke is pretty strong? No, it's stupid Overpowered against certain hands and disables Ambre effect. Really, just a pain to face in Standard or Extended.
Newer Cards, Kalindra is just annoying. Really, stalling games in Standard and Extended, and triple old then use all your pills on Kalindra. Really, it's pretty annoying.
Beeboy, the man who adapts, amazing card. But really... 7/7 with +2 power and copy opp bonus is pretty unnecessary, but whatever. He's just fine as he is, if you asked me.
Those are just my opinions on some newer OP cards.
