Kozilek's Pathfinder

A 5/5 for six is unremarkable, and that is the point: everything interesting about this Eldrazi lives in the repeatable colorless sink that strips a chosen creature of its capacity to block. The activation is unbounded, so on a board awash in Wastes or Eldrazi ramp it can peel two or three defenders away in a single combat, walking the same 5/5 body past a wall of chump blockers that would otherwise stonewall it. But the design deliberately wires that evasion to the exact resource the deck most wants for its bigger threats. That competition is the whole design: this is a way to convert leftover colorless into damage when there is nothing better to spend it on, not a play you make on curve. Each activation clears blockers rather than growing the body, so the payoff is always the same 5/5 connecting, just against emptier defenses. It earns its keep in the cluttered board state, the turn where the opponent has just enough bodies to gum up an attack and you have enough mana in reserve to make those bodies irrelevant. It sits at the workmanlike end of the Eldrazi roster, a swarm-filler that turns idle colorless into pressure and quietly reminds the opponent, every combat step, that the mana in your pool is never quite dead.
