Here’s the video that I made…
After watching your fight there are a few things that you need to work on as a Sadira main, some of these I am still working on, so don’t feel bad.
My first observation is your defense needs a lot of work. It’s fine to take damage if it helps you get in, but as Glacius hits very hard you need to make sure you’re not needlessly running into his hail and fists. Use Sadira’s maneuverability to dance around the screen and avoid attacks like hail (just as an example). It takes a lot of practice, but you’ll get there. If Sadira has instinct available and you get in, use it. Make them fear you. Even though Sadira is considered the worse character in the game, her Instinct is still one of the best.
In respect to the Glay fight. Glacius wants to keep you away from him. He’s most dangerous when he’s half way across the screen. Jumping HK and MK are really good at keeping Sadira away, but you have tools to assist you.
Jumping HK can be countered by Recluse. L. Recluse has a decent hitbox and can allow you to combo afterward. You should just block Jumping MK and then counter afterward.
A good Glacius will almost always have hail hovering over their head. A good Sadira can dodge these, even though it isn’t also wrong to take a hit, if it means you can get in.
As a Sadira main, you always want to be right over Glacius’ head. If they become too reliant on Glacius DP, you can do empty jump’s into block to bait it. Meaty jumps are also good as you can cross up. Don’t be too floaty.
If Glacius tries to use Shatter, just short hop.
So the key take aways are this…
Work on your defense.
Better utilize your instinct…
Glacius specific match up…
Use Recluse to counter jumping HK
Use Sadira’s Double Jump to bait DPs and dodge hail.
Stay close to Glacius and pressure him by using meaty cross ups.
If he pops Instinct… Use Sadira’s mobility to play keep away until it passes.
