Frost Ogre

Five mana for a 5/3 with no abilities is a bad rate by any era's math, and that is precisely the point: this is a vanilla creature pushed enormous in one direction and brittle in the other, a beater that swings like a freight train and dies to almost anything that touches it. The three toughness is the giveaway. It folds to most burn, trades down into smaller blockers, and offers nothing once early pressure stalls. Designs like this exist to cap the high end of a common-rarity aggro curve: the plain top-of-curve body a red deck reaches for when it needs another threat and nothing sharper is available. Calling it filler is not an insult; it is the job description. The card asks nothing of the player and rewards nothing in particular, distinguished from the long line of similar commons that has run through nearly every set since the game began only by the size of the swing it offers and the speed with which it can be answered.
