Which console are you on? it is almost impossible to critical K.O on the DS without special shots
if the gate cards are close to the boosters go on the boosters and it should give you enough speed to critical K.O them
Hah, I play DS. When I tried using the speed boosts in the Subterra field, I just bounced off of their bakugan, like you normally do.
Oh, and when you do a CKO shot, make sure it is a Bakugan that you would want to throw anyways
