Not of This World

A counterspell built backwards: instead of pricing the protection up front, it sets the sticker at a punishing seven mana and then erases the entire cost the moment you have done what the Eldrazi want, which is resolve something enormous. Aim a removal spell or targeted ability at a creature you control with power seven or greater and the seven-mana reduction zeroes it out completely, turning the card into a free hard counter wrapped around your biggest threat. That structure is the whole tension of the design: it is the most expensive way imaginable to protect a small creature and a literally free way to protect a colossal one. The reduction keys specifically off power seven, the threshold that separates the genuinely game-ending Eldrazi from everything else, so the card behaves less as general-purpose interaction and more as a dare. It does nothing affordable if your board is modest; it becomes a hard wall around your win condition the instant you have committed to the kind of creature that wins on the spot. The targeting clause is narrow in a useful way: it answers spells and abilities aimed at a permanent you control, catching targeted removal and a great deal of point interaction while leaving sweepers and edicts untouched. Being colorless, any deck can run it, but it only earns its slot in one built to deploy something with a seven on the left of the slash.
