Titans' Vanguard

Devoid usually reads as flavor: a way to make Eldrazi mechanically colorless without changing much about how they play. Here it is the payoff engine. The counter trigger doesn't care about creature type or mana cost; it cares about one thing, that a creature is colorless, and every devoid Eldrazi qualifies by definition. That turns a keyword mostly built to enable "colorless matters" cards into a self-fueling tribal anthem: cast this and the board grows, attack and it grows again, and the counter distribution scales with how many colorless bodies you've committed rather than with any single haymaker. The design ties the aggression to a deckbuilding constraint that pays for the recurring pump. You collect the trigger on cast and on every attack, but only your colorless creatures gather counters, so it rewards a board built almost entirely out of devoid and true-colorless pieces rather than a splash into a generic midrange shell. Trample and a 5/5 frame mean it can close on its own if the anthem never fires, but the ceiling is a wide colorless board where each combat step compounds. This belongs to the family of "cast" triggers that reward going first and often, the kind of design that turns tempo into a snowball, with the wrinkle that the snowball is keyed to a colorlessness of nothing at all.
