FAQ
I attacked with this Character and my opponent activated [Blocker]. If I use this Character's [Once Per Turn] effect to K.O. my opponent's Character that activated [Blocker], what happens to this Character's attack?
The battle will end without moving to the Counter Step.
Can I use this [Once Per Turn] effect to K.O. a Character other than my opponent's Character that activated [Blocker]?
Yes, you can.
