Give him a decent D4/D3, make his D1 6 frames. Give his ex anti-air throw armor and quicker start up ( Don't think his EX air grab has armor could be wrong). DF1 8 frames startup Fix F2 hitbox, make it quicker on startup, make clothesline safe and make EX + on block. .
You can use F4 into a special in the corner which is a combo that gets you plus 20 of damage. Don't remember the numbers right now. I use it a lot since he has a lot of corner carry in his combos so getting into this position isn't hard.
