Vs Kotal: Suppress your instinct to jump. Stuff that works against everyone else will not work against him. You lose air-to-air and he can push almost any button grounded and either low profile or flat beat you. Also he's going to back walk a lot and catch you if you're just running up or doing normals. You can yolo dive kick a lot against kotal and you should win trades against his b1 in active dive kick frames. Kotal should stop doing that and be a little more scared. Armor break everything. His options are slow and once he stops waking up, you'll have immediately bumped your win chances up a TON. You want Kotal on the ground and guessing. His normals will beat yours.
VS Tremor: He has no armor options to beat you. B33 or 121 will break all of his armor options pretty reliably. This has been an easier match up for me because you will beat him at point blank neutral and his zoning is good, but you can get around it if you're just a little bit patient. Throw out d3's and d4's like a fiend. Disrespect every window with your pokes. He suffers from not having a fast mid, and you can poke him out of any of his fast strings. Watch the back walk into f12 (super advancing 6f high). If he starts to catch you with the ex low crystal from you poking through every pressure window, just start to cross him up. You can get over the crystal into full combo.
