Olog-hai Crusher

A 4/4 with trample for four is above the plain-vanilla curve for red, and the clause that pays for it is not a downside on offense at all: this creature can't block unless you control a Goblin or Orc. That restriction encodes the flavor (a siege monster driven forward, useless as a defender when its handlers aren't there to command it) directly into the rules, and it does so with a tribal gate rather than a flat "can't block." The design turns a pure aggro creature into a signpost: it wants to be in a deck that fields Goblins or Orcs, and in that deck the drawback quietly evaporates. It is a familiar red trick, the aggressive body priced below rate because it will only ever attack, given a specific twist that ties the escape hatch to a creature type. On its own it is a beater that turns sideways every turn and never comes home; alongside the right tokens or a single go-wide anchor, it becomes a beater that can also hold a line. The gate is narrow enough to matter and wide enough to build around, which is exactly the tension it was made to create.
