I found an os a while ago against corner wake up DPs but I only tested them against Jin and I am sure they won't work against super fast DPs but at least it will help in the mirror match
After mousu in the corner do 2A 4B+C (barrier block) if the opponent blocks 2A,5B will come out, if he reversaled 2A will whiff and you'll barrier block the DP and punish and if he rolls 2A will catch him and auto-confirm to 5B
