Making assumptions is usually a bad thing so I figured I'd throw in some basic advice just to be sure lol. 2,2 is a fantastic string. It can be cancelled into an Ice Ball for a big combo, it can cancel into Slide for a low mix-up, 2,2,2 ends with an overhead, and 2,2,4 can create space if it lands and can cancel into an Ice Clone. 2,2 is fast, safe, has a monster hit box, and is really flexible.
If you already know all that, sorry, I wasn't being condescending just making sure. If not, hopefully that helps you in the future. =)
