The main thing I've found is that Neutral B is actually almost impossible for Inkling to handle. It's going to generally force constant jumping (or a lot of free %), which I feel like Wolf can probably contest with dash away Bairs, at the very least. If Inkling is in the ground, you can honestly almost never go wrong by just... shooting them. Even a training room AI set to fire it is much more difficult to get past without jumping that I'd have expected-- it's a really good projectile that you can definitely lean heavily on. Other than that, Bair is Wolf's best aerial, it seems, and Ftilt seems like you best general normal (especially as it can KO an Inkling at ledge here and there). Try not to over commit, as their combo game is the big problem... well, other than Wolf's recovery, but I can't think of any real solution to that specific conundrum.
