i'm sure every dante here has tried to xf a cold shower/weasel shot to save themselves only to have a prop shredder come out with no xf pause. this happens because you're actually kara cancelling the style change into xf. dante's style change moves are buggy/hardcoded... for the most part, they are completely uninterruptable when something else happens on the same frame when they're executed (have dante die on the same frame you do a prop shredder.. notice how he stays alive until after it finishes no matter what).
anyways, what gave me the idea was this post. i played around with it ever since it was discovered to see if i could break it, but nothing ever came out of it. then all of a sudden on wednesday, something hit me. i figured style-change stinger might work also. and it did. i also figured that maybe if i bold cancel it, i might be able to act during the super pause. and i was also right. it seems that whenever the move you're doing during the super pause ends and dante goes back to neutral state (or starts up a super), the glitch ends immediately. and while just cancelling in this fashion leads to lots of interesting (and broken) effects on its own.. 10stars was the one who figured out that just doing stinger > million stabs and cancelling out of that was much easier.
...and then it hit me. i immediately thought that maybe style-changes could be abused to maintain avoiding a neutral state, since million stabs is cancellable into launch which is cancellable into charge shots which is cancellable into stinger which is cancellable into million stabs, etc. and sure enough i was right.
the way this glitch works is similar to alpha 3's crouch cancelling to avoid neutral state. except here you are continuously using style-changes to avoid the neutral state and stay in THC startup super pause. leading to hitstun/blockstun infinites which have basically no escape options from anwhere on the screen (in the case of blockstun infiniting, xf guard cancel is not possible at all, pushblock can only be done once, and
crossover counter 'works', but... just wait for the video to see why its not a valid escape option)
