Furious Spinesplitter
The counter clause is doing something subtly different from the usual "grows when it attacks" damage engine: it doesn't care whether this Ogre is the one dealing the damage, only that each opponent took some. That decoupling is the whole reason it can scale past a one-on-one fight. In a duel it's a serviceable trample beater that gains one counter per swing, but the ability reads opponents plural on purpose, so a board that reaches multiple players in a single turn stacks counters accordingly. It also means the growth is not tethered to combat at all: a burn spell to the face, a ping, any incidental damage from another source keys the trigger just as well, since it checks a game-state fact at your end step rather than requiring an attack. The trample earns its keep because the body inflates on your own turn and then swings the following one, so a counter earned early is already threatening to punch through chump blockers next turn. The Gruul hybrid pips keep it castable in either color alone, which is the concession that pays for a snowballing threat: it wants a wide, aggressive board that spreads damage around, and it rewards you for having already committed to that plan rather than for building around the card itself.
