Space Marine Devastator enters the battlefield and immediately deals damage equal to the number of creatures you control to any target — a built-in, free removal or reach effect stapled to a body. In a Marneus Calgar deck that floods the board with token-generating Ultramarines, that trigger regularly threatens six-plus damage the turn it lands.
Best Commanders
Commanders with the highest synergy
Marneus Calgar
Marneus Calgar draws a card for every nontoken creature entering the battlefield, so Space Marine Devastator replaces itself immediately — and the token-dense board Calgar builds turns the Devastator's ETB into a credible removal piece or lethal reach.
Inquisitor Greyfax
Inquisitor Greyfax's vigilance anthem and tap-to-untap effect keep a wide board of creatures in play, giving Space Marine Devastator a large headcount to convert into ETB damage every time it blinks or re-enters.
Commissar Severina Raine
Commissar Severina Raine rewards aggressive go-wide strategies with drain effects, and Space Marine Devastator slots cleanly into that shell — adding a damage-on-entry threat that scales with the same creature flood the Commissar demands.
Soundwave, Sonic Spy
Soundwave, Sonic Spy copies instants and sorceries cast by opponents, but its real draw to Space Marine Devastator is the artifact creature typing — Soundwave shells often run enough creatures to make the ETB damage meaningful while Soundwave handles the card advantage.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Space Marine Devastator actually functions — multiplayer boards are wide, ETB damage scales fast, and token strategies make the trigger lethal rather than marginal. In Legacy and Vintage it's legal but unplayed; a five-mana 4/4 with a conditional ETB ping doesn't compete with what those formats offer at that cost. Oathbreaker can support it in the right wide-creature shell, though the 20-life starting total compresses how much the damage trigger matters.

Price Context
Current price
$1.07 cheap tier
At $1.07, Space Marine Devastator sits firmly in the bulk-rare tier — cheap enough to slot in without deliberation. Demand is narrow enough (Warhammer 40K Commander decks specifically) that the price is unlikely to move significantly in either direction.
