Fraud at Smash
Mii brawler really isn't that threatening guys .-. Has trouble approaching good walls, can't kill you in the unless he reads a bad airdodge, don't get grabbed near a ledge at 40, and challenge his air approaches with invincible/ disjointed upsmashes. If you can fight mario, you can first Mii Brawler, just make him force you to fight, not the other way around.
