Since you asked, here’s some things I noticed while watching.
- Never do shadow influence as a level 4 ender. It should only be used as an ender if you absolutely need the full knockdown time/wrath refill. Unless you’re empty, a level 4 influence ender should give you enough time for both a mixup and full wrath regen - level 4 leaves them on the ground for the same amount of time as the shadow version. The meter is better spent in neutral or on resets.
- If Rash tongues in at Hisako and she blocks the tongue, she can almost always down+MP him as a punish. Don’t let him approach like that for free - unless he comes in at a crazy angle, that ish isn’t safe.
- Don’t run into hail from full screen. If you’re going to take a hit from a hail, better to take it in the air. Hisako’s dash is also really susceptible to getting tagged en route - it’s fast and low profiles, but it’s a hard commitment. Dashing too much at Glacius is just asking to eat a cold shoulder or shadow.
- Hisako should never eat a shadow counter when she has more than 50% wrath. Get into the habit of mashing 3P whenever you see the screen freeze. Doesn’t matter if you have wrath for the cancel or not, this should be an instinctive reaction when playing Hisako.
To be honest though, that Glacius/Sako fight seemed more like bad decision-making to me more than anything. I think the biggest MU specific thing you’ll want to work on is trying to avoid shatter a little better - Menzo hit you with nearly every one that he threw out. He was definitely covering them well and forcing you to juggle multiple threats while he tossed it out, but still, you’ve got to be able to react to that pillar of light against Glacius or you’re going to get dunked.
The more general note I’d have (and part of why I think you got caught in that vortex repeatedly and went for some perhaps ill-advised counter breakers) is just that you need to work on your patience. Zoners in general tend to get a lot of their damage by punishing people who’re trying to get in, and Glacius is no exception to that. Trying to rush in is what he wants you to do, so don’t do that. Glacius doesn’t have anything he can really threaten you with once he gets outside of lance/shoulder range - shatter is reactable, and he shouldn’t ever be able to summon more than a single hail at a time without being punished for it. Make him try and figure out how to pressure you, and then use the things he does to try to apply that pressure to punish him. If he wants to call hail, descent behind him (even if you’re late you wind up more or less at neutral, and his hail is primed to come out in the wrong direction). If he tries to shatter, jump or shadow through it on reaction. If he wants to play inside cold shoulder range, then wait for the lance->something or raw cold shoulder and go from there. Basically, don’t spend your life trying to bully your way in if you can help it. Wait for him to do something you can react to, and then use that to get in on him.
And if you do have to bully your way in, I recommend wall jumps. Covers more ground, and can’t be punished into full combo. It’s fine to spend life to get in, but you want to spend it in ways that don’t have you eating full combos into knockdown setups.
Hope that helps
