Hell's Thunder

Three mana for a 4/4 flier with haste is a price no permanent body has a right to ask, and the self-sacrifice at the beginning of the end step is the entire reason it can: this is a burn spell wearing a creature's clothes, built to attack once and leave. Four flying damage on the turn it lands, then it is gone before it ever has to hold the ground or block. What makes the design sing is that the corpse is the second half of the spell. Unearth buys the same four-damage swing again at a steep premium, but only once: the card returns with haste, hits, and exiles itself, so you are charged a full second time for a threat you do not get to keep. That rationing is deliberate. Recursion that lets a body loop indefinitely warps board states; here the exile clause caps the engine at exactly two beats, paid for in two separate, expensive installments. The graveyard half also doubles as a holding pen against sorcery-speed sweepers and targeted removal aimed at the battlefield, since the card is only a legal target on the turns you choose to make it one. Both halves want the opponent low enough that eight points across two windows closes the game, which is the company unearth keeps: cards engineered to die well, valued for the damage they deal on the way out rather than the position they hold.
