Maister, unlike most Mr. Game and Watch players, has a very aggressive and fast-paced playstyle, centred around quickly throwing an opponent into disadvantage and sealing out stocks while taking little retaliation in return by smothering all their options. His clever usage of throws and aerials, especially forward Air, which was thought to be one of the worst moves in his kit, along with his proficiency in edgeguarding and very strong combo game, gives him one of the most, if not the most, oppressive neutral and advantage state of any player. His disadvantage state isn't lacking either, commonly living up to 150% or higher as the third lightest character in the game. Notably, he is one of the few players who uses GnW's smash attacks to bait and condition his opponent due to their low ending lag, playing into his overall strength.
