Decisive Denial

The pairing of a fight spell and a soft counter in one card is a specific answer to a specific problem: green-blue decks that want removal but hate holding dead cards. A fight effect needs a creature on your side of the board and a target worth punching, while a counter wants an open mana pile and a spell on the stack; the two modes almost never go dead at the same time. When your board is developed, the fight half turns your fatties into removal at instant speed, dealing damage without ever attacking. When you have nothing down but the opponent is casting the planeswalker or noncreature spell that swings the game, the Force Spike side steps in for the same two mana. The counter half is deliberately soft: it taxes three rather than hard-answering, so it degrades in the late game and rewards casting it early or on-curve. That is the balancing lever. A card this flexible could easily have been oppressive as a two-mana catch-all, but tying each mode to a narrow window (creature-plus-creature, or a noncreature spell on the stack) keeps it from doing everything at once. This is the modal instant green-blue has wanted for a long time: fixed removal for a color pair that traditionally lacks clean answers, folded together with the interaction blue always brings.
