Homo MU. Homo Peach. Homo timeouts.
Be homo when you have a lead, Wario sucks at approaching you.
Don't airdodge, just loldair and hope he doesn't get the uair timing down. If he even tries to string, just homo nair 'çause you mess up any followup he attempts to do.
EXAMPLE: If he tries to nair > grab you at low percents, just lol@him and nair.
Whenever he does something on you shield and tries to play funny, just nair. Just nair.
Be homo and turnip camp.
@the random guy who said Wario has a lot of range in the air: that's false. Just uair and SORTA bair, and bair is crap in this MU. Don't ever say fair has a lot of range because it doesn't.
Just spam safe stuff in this MU until it hits, while Wario frantically tries to do the same thing, only with a much worse risk-reward ratio. Not a ratio 'cause I'm biased, MU is just mad homo to the extent of me not even caring about my usually oh-so-formal English anymore. Get@me.
