Storm God's Oracle

A creature that is really a delayed burn spell, with its own kill switch built in. The pump ability drains a point of toughness for every point of power it adds, which means the same button that swings harder is the fuse that eventually detonates the body: three activations and the toughness reaches zero on your own turn, firing three damage at a target you choose. That self-immolation is the mechanism, not a downside. It turns a fragile shaman into removal that walks onto the battlefield first and goes off second, once, whenever the timing suits you. What separates this from a plain creature-as-removal is how many roads lead to the same payout. Trade it in combat, chump a larger threat, feed it to a sacrifice outlet, or grind it down with its own ability; any path to the graveyard collects the three damage, and the built-in +1/-1 means you never have to wait on the board to cooperate. The design belongs to an older Izzet tradition of bodies that would rather die than sit still, treating a creature as a spell that happens to block for a turn or two on its way to the yard. It asks nothing of a build-around and little of the manabase; the payoff is a one-shot three-point burst you can schedule, welded to a body that trades up while it stalls.
