Errr.
Why are you telling me to stfu?
Anyway, SC is a different breed of fighter. Infinites are much harder to come by in 3-d fighters and they give much bigger advantages namely because you have a health meter so an infinte alone can kill. And this is extremely easy to do. Plus Ivy already had all the tools to be top tier. She has great pokes, can fight at any range, can shut down side stepping, and has insane command grabs. This infinite put her over the top.
You can't compare Dedede who manages to get by on a few really good moves and a CG to a character that has pretty much EVERYTHING you would want in a character that also happens to have an infinite that is super easy to set-up.
Do you realize the insane mix-up potential off of this infinite? Say it isn't banned. Ok, a veteran who knows about the infinite would always block standing when they see Ivy crouching. Guess what though? Ivy has two command grabs that can take about 1/3 of a life bar. So if you ALWAYS block standing when Ivy does a move that forces her to crouch then she essentially gets a free command grab every time. You could attempt to break the grab, and it will be easier if you know it's coming, but then another mix-up with low pokes can occur.
Do you not see how f*ckin deadly this is?
BTW Ivy also has an attack loop when her opponent is against the wall.
Edit: Infinite on counter hit still scares the piss out of anyone. It's not hard to get a counter hit really. You just have to hit someone when they try to do....anything at all.
Also Ivy was in coiled stance in the vid. She can't do command grabs in that stance. But if she has that launcher move in sword stance then the mix-up is still viable.

I want you to try going Diddy on my Marth son.
He is hungry for some monkey brain soup.
