Ursine Champion

The pun is the whole pitch: a Human Berserker that pays six mana to literally become a Bear Berserker, gaining +3/+3 in the bargain. Strip the flavor joke and you are left with a 2/2 for two whose only text is a wildly overpriced pump outlet, the kind of mana sink stapled onto commons to give an aggressive board something to do when the curve runs dry. Six mana for a one-shot +3/+3 sits far above the going rate for a pump effect, and the once-each-turn clause caps it at a single transformation on any given turn no matter how much mana is available. That makes the ability a floor, not a plan: it exists so the body never reads as fully blank in the long game, not because anyone builds around the bear. The honesty of the design is in its modesty. It is a two-drop beater first and a flavor gag second, with the activation priced precisely high enough that it almost never decides a game on rate alone. The card holds out a small reason to keep swinging, and a smaller smile when the transformation actually fires.
