Honestly what i have learned is that you must learn your characters normals first, Carmine's normals are literally amazing lol and i think seth really can't deal with a character witch attack range better than his. So try gaining vorpal so you can bait out one of his attacks and chain shift at the right moment for a good punish or combo punish that will lead into either hard knock down with the 6-C for oki,mix-up, and vortex or just all three with the hard knock down. Remember block until you see an opening, also note that carmine literally throws his health at you lol just to keep you in pressure so when you do punish him you might bring his life down alot faster because he is also doing it for you!
