Grist, Voracious Larva // Grist, the Plague Swarm card art
Grist, Voracious Larva // Grist, the Plague Swarm transforms into a planeswalker that mills, makes tokens, and drains opponents — all on a two-mana body that flips immediately if an Insect is in play, which in dedicated shells is turn two. Doubling Season lets it enter with enough loyalty to ultimate on the spot, and Zask, Skittering Swarmlord turns every milled Insect card into free value, making Grist's mill ability absurdly recursive.

In Commander, Grist, Voracious Larva // Grist, the Plague Swarm earns its slot in any Insect or graveyard-centric black-green shell — the flip condition is trivially met, and the planeswalker side provides mill, tokens, and drain on a single card. In Legacy and Vintage it sees fringe play in Dredge and BG Depths builds where the Insect tribal clause is irrelevant but the two-mana planeswalker body is not, and it operates cleanly alongside Doubling Season in any shell that can support it. Modern legality makes it theoretically available to Yawgmoth or Elves variants that touch black and green, though it hasn't broken through at the competitive level there. Oathbreaker lets it serve as the planeswalker signature piece for graveyard-themed builds, where its repeated mill and drain ultimates quickly.
