Yeah, use the folder with the panlouts and snakes. Ignore your health and fire away with the buster (you don't need an S rank, you just need to kill him fast). Punch out as many holes in the floor as possible and then use snake chips. The snake chips really add up damage.
For Kingman, when the knight piece tries to jump on you, step back and punch a hole in the floor, the piece will fall through the hole and you won't have to worry about it for a while (unless he uses a plan change).
Jack of all trades.
Master of none.
