Stalking Drone

A green two-drop that asks for a different kind of mana than the one that cast it. The 2/2 body pays its own way, but the activation runs on colorless, the mana symbol an entire Eldrazi-era archetype was built around. That makes this less a green card than a colorless-matters card wearing a green casting cost: it wants Wastes, it wants a producer like Mind Stone or an Eldrazi scion cracked for colorless, and it rewards a deck that has consciously slotted a colorless source into its curve rather than treating mana as fungible. Devoid does the quiet structural work here: the printed card is colorless, so anything that keys off a creature's color reads it as a generic Eldrazi Drone, even though it still costs green to cast and keeps a green color identity. The pump is throttled to once per turn, so it never becomes a mana sink that runs away with a game; it is a small, repeatable bump that turns an even trade into a favorable one and lets the body survive a block or trade up. The design teaches as much as it fills a slot: colorless is its own resource, and a deck that respects it gets a creature that grows on a budget the rest of the table cannot easily pay.
