Space Marine Devastator

The two mechanics here are pulling in the same direction, and that coherence is the design's whole point. Squad turns a single cast into a scalable wave of bodies by paying the two-mana tax as many times as your mana allows, and Grav-cannon fires an artifact-or-enchantment destruction trigger on each entry. Because every token created by Squad is a copy that also enters the battlefield, each copy carries its own Grav-cannon trigger: pay the tax three times and you are not just deploying four 3/3s, you are stacking four separate destroy-up-to-one-target instructions. That converts a narrow single-target removal effect into a repeatable board-wide answer scaled by the mana you sink in, which is a clean way to give white a flexible artifact-and-enchantment sweeper without printing an actual Disenchant-on-a-stick. The "up to one" wording matters: with no legal targets the triggers simply do nothing, so the card never strands itself when the opposing board is clean, and the tokens still land. It is a straightforward expression of white's rank-and-file identity (many small soldiers, incidental disruption) built so that the more you commit, the more the disruption compounds. The Astartes flavor and the go-wide math line up exactly: a Devastator squad is meant to arrive in numbers and delete hardware, and the rules text does precisely that.
