Lab-honed combo execution plus live mixup guessing against adapting human opponents.

Execution · Competitive PvP
A platform fighter where reading opponents and precise execution both drive victory.

Long combo routes and tight conversions demand serious hands
Super Smash Bros. for Nintendo 3DS
precise inputs and combo execution required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Skullgirls: 2nd Encore
Mixups and resets only work by out-guessing a human
Super Smash Bros. for Nintendo 3DS
reading opponent habits and mixups
Super Smash Bros. for Nintendo 3DS leans a little harder on variance, though the gap is small.
Skullgirls: 2nd Encore
Fully deterministic fighter with nothing hidden
Super Smash Bros. for Nintendo 3DS
item spawns add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Skullgirls: 2nd Encore
Team composition, assists and combo theory go deep
Super Smash Bros. for Nintendo 3DS
matchup knowledge and combos solvable
