His first form and secret project to stall. Tag along and his response gives your opponent a blank character. Not too sure if Kuzuryu-reppa should be in here becauses theres no momentum generation. So high plasma beam seems to be the logical kill card. If people dont know what the character does here it is.

First Form commit: Until the beginning of your next Combat Phase, after an attack is played , it gets -2 damage. (minimum 1)

R commit, commit 2 foundations: After your opponent plays an ability on their character card, cancel that abilities effects. That Ability may not be played for the rest of the turn.
