As I've said already, Air Teching is important in this game. If you don't do it right, you walk into a reset.
For example, Celia II has no anti-air really besides her iffy f.5C, but Celia's 2C goes nice and high and is air unblockable.
So, if she can get you to tech into the air in the corner, she can wait for you to come right back down and land on it.
I've been teching according to the angle of my opponents anti-air options so I won't get caught or re-juggled.
Teching out the corner actually gets me in more trouble than neutral teching downwards and throwing out a normal during my descent.
