I have a very basic style against wario that seems to work.
Vary short and full hops with reverse uairs
It's a quick fast attack and it makes for an annoying approach on wario's part
You adjust your jumps according to what wario is doing. Don't put yourself in a position where you're directly above him though. Unless you did a rising reverse uair past him and he whiffed trying to counter it
In that instance you can fall with a nair or fair
If the wario airdodges the uair, you're still left in a good spot because the uair will end before his airdodge finishes. And in most cases you won't be level with him after finishing your uair
The REVERSE uairs do fairly well against wario's aerials. That's if you time them properly.
If the wario doesn't know how to deal with jolt spam, then use it. Most do know how though so the reverse uair works on those types.
From the backwards position, you can always do turn around jolts to kinda mix it up.
As far as the bite is concerned... the way you'll be jumping around with the reverse uairs, it will make it hard for wario to line up with you to get it off. And the starting point of the uair will catch him at the bottom of his body as you're rising.
If you've double jumped and the wario is positioning himself below you, just use a QAC away from him to avoid trying to fight your way back to safe ground.
If he attempts a fsmash or dsmash while ur jumping you can land and utilt
Basically you're using the attacks that are the hardest to punish. Doing this long enough will lead to oppurtunities to get off harder hitting attacks.
Most of the time you'll be setting up nairs and dairs with the uair though
And to those who say it's pointless to uair like this.
Uair can do 5-6% each hit. Two of them alone is 10-12% that's damage not to be taken lightly
I may edit this post later with how to deal with wario off the edge.
Some of you will find this useful.
Others will wait for Anther to co-sign and then you'll find this useful. Either way I'm sharing
