Hellspark Elemental

Three power for two mana arrives with a built-in expiration date: the end-step sacrifice means it gets exactly one swing before it dies, no blocking, no chump duty, no second attack. That clause is the price the rate pays, but the design's real trick is that dying is not a setback. Unearth buys the same creature a second time for the same cost, returning it with haste for another three-damage hit before it exiles itself. The card is engineered to be spent twice, both times as a clock and never as a board presence; trample ensures neither attack gets blanked by a single chump. Functionally it reads as six trample damage split across two turns for four total mana, paid in installments, with the body never lingering long enough to be a liability or an asset on defense. The structural ancestor is Ball Lightning, the prototype for the hasty all-or-nothing red attacker that vanishes at end of turn; unearth converts that single suicidal charge into a two-installment burn engine that happens to be a creature. It is burn pretending to be a body, designed for decks that want their threats to behave like spells: deal damage, leave nothing for an opponent's removal to profit from, and return from the graveyard on schedule.
