I found some sweet tech a few months back, before NEC, and I think it's about time I share it with you guys. It's only available to Yoshimitsu and Hilde. As many of you know, after the patch, backstep and sidestep became -20 and Project Soul did everything they could to make any workarounds like A, B, and K cancelling or fast UB cancels slow down if done during a movement so that they do not allow you to block earlier. However, it wasn't enough.
Yoshimitsu and Hilde suffer the same animation slowdown as others, but for some reason, their animations will stop early at certain point if an attack hits them, and they will block it. This is clearly a glitch, as it is not the same as normal guarding, where just pressing G instantly allows you to do other things. No, here you're stuck in the animation unless an attack comes and interrupts it early. You can't crouch block or duck under highs, lows will just hit you and you'll magically block highs that were supposed to catch your backstep or sidestep. Sound familiar?
Yes, this is a lot like the Step G in SCII, though not nearly as good. You magically block things but are vulnerable to lows and throws. In SCV, this "Step bG" only takes your movement back to pre-patch safety, while stopping the movement short. Instead of 20 frames of vulnerability, you get 16 frames and then you'll start blocking things.
So how's it done? Both Yoshimitsu and Hilde can do it by stepping or backstepping and doing their B attack guard cancel, or bG, while Yoshi can do it with aG and kG. Yoshi's bG is especially good since it makes him backstep further with the animation while aG is recovers faster for if you want to whiff punish better. Hilde's bG recovers pretty quickly, so now Hildes can charge and recharge C2A subtly and safely while using her excellent movement.
You can choose to do the bG immediately after tapping the step movement or in the middle. Getting a -16 backstep/sidestep results in a very small movement. You could get hit by i16s that wouldn't have if you had done a normal backstep. Getting a -18 backstep is more practical when up-close.
So by now you're thinking "psh 2-4 frame difference, what's the big deal?" Well if you knew your frames and backstep-catching setups with various characters you'd realize that you pretty much break that part of the game's design with this technique. Patroklos can no longer catch you with 66B backstep catching or 44A sidestep catching at low advantages. Siegfried aGA on block can no longer trap you with another aGA threatening to hit your step or a 3B hitting your backstep. Xiba can no longer contain your movement with the threat of CH 6A quite as well. Pyrrha AA hit into 66B can be backstepped and blocked. And I'm sure there's plenty of other situations where it matters. And the question I always ask with weird defensive techniques is "is it better than JGing?" In this case, yes, since you move away from your opponent instead of standing still, and you have a chance making things whiff. Note that you can't step and JG with this technique, it's always a normal block.
