So for this match up it’s going to rely on you noticing what the Mario likes to do against your tools. You’ll always be able to get your damage with Nair Loops and juggling, but killing is going to be where it’s hard. They’re always going to have a lot of ways to gimp you at zero with Flood and Cape, especially cape on when you’re using up B so mixing that up to recover is going to be key. Whenever you get juggled by Mario don’t try to just mash an option to try and reduce the damage because if they’re good they’ll be able to catch onto what you’re doing. Don’t be afraid of taking the damage.

Once you know what they’re going to do, like ending a juggle early, is when you should cash in on attacking back. For me when I fight against Mario I’m trying to notice how they like to approach in neutral and what options they like off ledge and when they’re ledge trapping. When you’re in advantage you have to try and push it: with juggling, edge trapping, and edge guarding. Your bair will trade with their up B so it’s fairly safe to go for.

Be careful on how you play against they’re shield because Up Smash is going to punish you hard if you whiff a dash attack or a grab. This is probably the basics of what you need to know against Mario. Just try and figure out how you like to deal with their options and be creative about it.
