If you are in the corner when you block a spin chain, you can fd and riot stomp punish.
if he gets you in a stance, then tries to go back into stance, wakeup gunflame. He can't send the chains out because they hurtbox goes out early. You can then run up and dp or mash jab, whatever. If you dp and it whiffs, you still get to throw him because going out of stance takes so long
