If Lucario's being shine gimped or bair gimped he's 80% of the time screwing up one recovering properly.
As a whole, most of the time Wolf outcamps lucario, until mega percents then it's standoffish, even then Lucario will probably be forced to approach
I really like Wolf's onstage control game it's so freaky.
We miiiiiight have uthrow CG because we haven't fully tested buffering/standing pivot stuff, but atm we don't have a realistic one, it's pretty much a tech chase scenario.
Lucario bair and fsmash is really good in this MU, very tricky to punish if used properly. Lucario has better anti-air stuff than given credit for.
wolf bair is annoying, very good zoning tool. AC fair can do some nasty stuff too.
lucario juggling is golden for Lucario in getting damage, has some pretty decent setups.
Offstage, I'd say Wolf doesn't do as well as Lucario in most cases, although wolf has the capacity to pressure Lucario when he's on the ledge with some annoying stuff. Lucario has a holiday with wolf offstage imo, as I personally think Lucario's edgeguard game is very underused.
Wolf dsmash is gewd, keep this thing fresh or this MU will not like you.
I'd say the evenish realm is reasonable.
You will hate Lylat (for obvious reasons), JJ (If it's allowed in your region), Frigate Orpheon, YI, and maybe Castle Siege for this MU.
I think your best neutral would be BF because I think Wolf's platform control is better than Lucario's in this scenario. FD lets you camp, but it gets icky when it comes to trying to kill Lucario on that stage.
