Tyvar, the Pummeler

The tension in every overrun effect is that it lands on an empty board too often, or the payoff scales off card count instead of the thing that actually wins games: raw power. This resolves that by paying you back for the biggest creature you already have, doubling down rather than spreading thin. The anthem reads off greatest power among your creatures, so a single fatty pumps the whole team in one swing rather than rewarding a wide but toothless board. And because the ability carries no timing restriction, five open mana is a live threat on either turn: swing for lethal on the attack, or hold it up and turn a bad block into a blowout. Quieter engineering hides in the tap ability, which changes what the body is worth. Tapping a spare untapped creature buys indestructibility, so a mana dork, an idle chump, or a vigilant attacker that never turned sideways becomes a shield that keeps a 3/3 legend alive through a wrath or a combat trick. That the finisher and the survival tool share one package matters, because the survival cost is a resource you would often not otherwise spend. The Tyvar planeswalkers before this were mana-and-untap engines built around elves and ramp; recasting the character as a creature reframes him as the beatdown payoff those decks were always missing, the piece that turns a green board into lethal without dedicating a slot to a standalone overrun spell.
