Start with a Sub at 1 HP. If he attempts to Snatch it, employ Brick Break.
If he has a Substitute, utilize Arm Thrust. But if you do not have Substitute and he does not attempt to use Snatch or you are otherwise prevented from using the move, use Substitute at 1%. Otherwise, default to Brick Break.
Substitute(1%)/Brick Break ~ Arm Thrust/Substitute(1%)/Brick Break
