Ruinous Intrusion

Naturalize and its many descendants have always felt like a card you spend at a loss: you burned a card to answer a permanent that may already have done its damage, and got nothing but the removal in return. This design attaches a payback clause scaled to the target's size. The bigger the thing you exile, the bigger the payout, so vaporizing a five-mana artifact hands one of your creatures five counters at instant speed. That coupling is the whole point: it converts a reactive, occasionally-dead disruption spell into a growth spell that happens to disrupt. The instant-speed timing carries real weight here, letting you hold it up as an answer to a game-ending artifact or enchantment and choose your moment to fire rather than tapping out at sorcery speed. The tension is honest, though. Both halves are mandatory and each needs a legal target: no artifact or enchantment on the board, and the spell sits dead in your hand with no permanent to feed the counters. It rewards a board where both clauses line up and asks you to accept the awkward draws in the games where they do not. The counters it distributes are permanent, unlike aura-based or equipment-granted size, so the growth it produces survives any effect that removes the source of your other pumps. It is a removal spell that leaves your board bigger than it found it, provided the board cooperates.
