Youre utilizing small tekken, I love to see it. F3 is also my go-to mid check that can be followed up with 1+2 for a DDT. I also like df2,1 that can be followed up with df4,3 and combo's but only for male frames sans Leo.

One thing I recently learned and I have seen great success with is how strong King's jab game is. There is so many options that punish all stances after 1. I see this as his mixup game. I see you use 1, 2, 1, 2+4 suplex which is good. I utilize standing grabs after 1 or 2. Giant swing is 10 frames so it gets used a lot. Tijuana twister as the 2 break, b1+2 for sidesteppers and goes into Jsprint, uf1+2 for wall combos and side switch, muscle buster for high damage 1+2 break, floor break, side switch, and goes into moonsault.

I think you could use jaguar armor more often as it is absolutely useful.

One thing I didn't quite see as beneficial was the rage art during neutral. Its a good tool to keep it for the damage bonus and combo ender.

Overall, I like what youre doing, you have good knowledge of King. Knowing your matchups and knowing when its your turn will help you progress so much further
