Arni Brokenbrow (KHM-310) is a Legendary Creature — Human Berserker from the Kaldheim set. It has haste and a Boast ability that can set Arni's base power to 1 plus the greatest power among other creatures you control until end of turn. The Boast ability is usable only if Arni attacked that turn and only once each turn, letting it potentially become a large attacker for a single combat.
