As I mentioned in the matchup topic, the hardest corner games come from Kano and Jade. 222-clone is my personal default ender in the corner, but Jade can bust clones with armor or invincible and go right through. She has a ton of mixup options. Kano can wild-ball above and behind you. If you are you going to corner a Kano player, this is a grand exception. You're better off going sweep distance and blocking. Keep your thumb right on 2 when you do this just in case he chooses to run up and grab you or jump over you so you can switch from block to 22-freeze-combo.
