it wasnt a very solid guy imho, it was just lack of match up knowledge. From my experience (i´ve played a very good guy, a friend of mine used to main it) u have to learn to fight crouching and by that i mean no jumps towards (i mean it), guy´s st.hk and st.hp are a very good AA (as u can see in the last video), air to air j.mp and the elbow are just gdlk u cant beat it with target combo, dont get me started with the insta izuna drop that shit is crazy, in the other hand if guy jumps u can use st.mk and df.lk (and this is why i played kikosho in this MU), but if he uses the flips or runs u have to use either cr.mk or cr.mp, i love the cr.mk in this match up, anytime he use the elbow u can dodge it and throw him, and depending on the timing, guy actually lands on top of the cr.mk, making it super easy to land a cr.lk into EX LL, learn cr.mk links.
Every time u block a hozanto u can punish it with super, anytime u block and EX hozanto u can punish it with a cr.lk or cr.lp into BnB. In offense this MU works pretty similar to the rufus MU, by that i mean dont rush it if he have any EX meter, bait the wake up EX tatsu/Ex run, which is quite easy cuz guy´s EX tatsu cant hit you while crouching and actually u can meaty cr.mk any other version of the tatsu for a free punish (as u can see cr.mk is a very good tool in this MU); once guy has no meter RTSD. The main objective in this MU is to either have super and punish any slide/hozanto/etc. or to simply corner him, in there u can rape him… but if by any reason u are in the corner u are in deep shit, cuz guy can use a deadly mix up/reset game, if by any reason u are being reseted after his bushin chain combo use cr.lp as soon as u land, this way the bushin flip cant throw you, trust me on this.
Learn to tech properly, by that i mean Late OS crouch tech and Standing tech, very good guys are insanely good at frame trapping, guy´s CH cr.mp is something u have to respect, he can dish out +400 dmg from one counter hit, learn to Block and to Tech. Finally a few things to remember, dont ever use EX sbk in wake up (or at all actually) guy can stuff it with elbow or j.mk, if he throws you with the knees and then he jump twice block, that´s a safe jump, and a very tricky one, in the second jump he can use j.mk for a cross up, but he also can use elbow to fake the cross up, be aware; dont bother with kikokens aside blockstring (specially you, i never saw you use a single blockstring) u should not throw them, U1 have a very weird range and can use it to punish a silly kikoken.
TL;DR learn to fight crouching, learn to use cr.mk, dont jump, dont throw kikos, use U2, frame trap him, and learn to block/tech properly
