Seismic Strike

The reward for going mono-red, sold by the mana value. Most red removal of its era priced the effect into a fixed number: a burn spell deals two, or three, or four, and the count never changes regardless of how you built the deck. This one ties its damage to the one resource a dedicated red deck already maximizes, so it scales as a function of deckbuilding commitment rather than mana spent. The cost is conceptual, not literal: the spell does little in a two-color manabase and asks you to forgo splashes to keep the Mountain count high. By the midgame in a deck built to feed it, the same three mana that buys a fixed burn spell here buys a kill on nearly anything with a body. The instant speed is the part that makes the gamble worth taking, letting it sit open as a combat trick or a response to whatever attacks rather than committing to a target on your own turn. It belongs to a small family of payoffs that reward Mountain-count purity, a design lever Wizards has reached for periodically to give mono-color builds a reason to stay disciplined. The ceiling is real and the floor is a dead card; the spread between them is exactly the deckbuilding question it asks.
