Bound (B!) moves (slam opponent down to continue combo/use Tag Assault)
second hit from ss+2,1
uf+4; 1+2,2; d+2 B! d/f+1; f+2,1_GS
So far the best way I’ve found to use him in the middle of a combo (during Tag Assault) is his 3+4, 2.
Some notable moves/pokes might be d/f+1 and d/f+4. Also throw in a d/b+3 to keep your opponent honest (keep them from just blocking high all day) BUT if blocked it’s punishable.
