^ One of my favorite matchups xD
Get into the habit of not fsmashing unless you know for a fact that you will hit. It can really save you in some matchups (Snake ._.), and has some definite use against wolf. What I do is basically spam SHFF bairs and punish their attempts to punish my SHFF bairs... Yeah. Not interesting. There's a lot of other stuff you should do too obviously (, but the basic idea is to be defensive until you KNOW you can be offensive. Wolf is a great punisher, so don't get punished. Shine gimp like crazyyyy.
So play safe, punish, and gimp, basically.
Man, I'm really out of it lately lol, sorry for the sub-par explanation.
