Static Snare

Reactive removal that inverts its own price against the board it answers. The base cost looks steep enough to shelve, but every attacking creature shaves a generic mana off the total, tying the price directly to the exact game state a control deck least wants to see. Fire it in response to a full swing and it strips the biggest attacker (or a problem artifact) while wrecking combat math for a fraction of the sticker cost; the more an opponent overcommits, the cheaper their own aggression makes your answer. That is the whole design logic: the card is at its most affordable precisely when you are under the most pressure, and at its most expensive when nothing is attacking and you have less reason to want it. Note the floor, though: the reduction only ever touches the generic portion, so no amount of attackers gets you below the . The exile is the enchantment-anchored, temporary kind rather than a permanent removal, doubling as a reset for something you need gone this turn (a fresh threat, a mana rock powering a combo) with the caveat that destroying the enchantment hands it back. Flash is what makes the reduction pay: a sorcery-speed version would let the attack resolve and the board rebuild before you ever cast it, while instant speed lets you keep the answer live and wait for the swing that discounts it.
