Umaro, Raging Yeti

A random modal trigger is a design gamble, and this one leans into the volatility rather than sanding it down. At the beginning of combat on your turn, one of three effects fires by dice roll: a +3/+0 with trample for your other creatures that converts a wide board into a lethal swing, a discard-and-draw-four that refuels an empty hand, or five damage aimed anywhere. The point of tension is that you never get to pick. A card that reliably granted an anthem, or reliably drew four, or reliably burned would each be a known quantity to build around; folding all three into a one-in-three roll means the deck has to be content with whichever one lands. That surrender of choice is what pays for the ceiling. The anthem mode wants a crowded board, the draw mode wants a spent hand, the burn mode wants a target worth five: commit to one and the other two become live upside; build to accept all three and you have a haymaker that rarely does nothing useful. The 6/6 trample body underneath is not incidental. Even on the roll that whiffs against your plan, the card still swings for six on its own, and the trigger only fires at the beginning of combat on your turn, so the variance is bounded to your own attack step. It is a payoff piece that asks you to make peace with the roll in exchange for a package no single-mode card at the cost could match.
