Viscerid Drone

A blue creature that destroys creatures: that inversion alone tells you which set this came from. Alliances built much of its identity on the snow-permanent mechanic and on color-pie bending across the allied Ice Age pairs, and this little Homarid is a textbook artifact of that experiment. The cost is paid not in mana but in attrition: you tap it, feed it a creature, and feed it a Swamp from the battlefield, getting back hard removal that dodges regeneration entirely. The snow-Swamp clause is the design tell. With an ordinary Swamp it spares artifact creatures; pay with a snow Swamp instead and the restriction lifts, the second mode reaching anything. That gating shows what snow was meant to do as a resource in this era: a deckbuilding tax that rewards committing your manabase to the supertype, with the upgraded ability as the carrot. The friction is steep by modern standards (a creature, a land, and a tapped body all spent per activation), and that steepness is what licenses the effect to be unconditional removal of a kind blue almost never gets to touch. It is repeatable Terror lashed to a sacrifice engine and a land-destruction cost, sitting on a 1/2 in the wrong color, a fragment of cross-pie design from a period when Wizards was still figuring out where the lines should be drawn.
