Knockback Knights
Two knights, one keyboard, no subtlety. You get a hop and a swing, and both of them move you — the recoil off your own sword is half your mobility, so every fight is a shoving match where the arena does most of the damage. Take the solo ladder against AI knights that each fight differently, or hand half the keyboard to whoever is sitting next to you. Six arenas keep the ground untrustworthy: crumbling rooftops, iced bridges, catapults with no sense of fairness.
