Corroding Dragonstorm
A drain spell with a rubber band tied to it. The enter trigger does the work of a small Blood Artist burst (two life each way, plus a Surveil 2 to smooth the next several draws), but the reset clause is what turns a one-shot enchantment into a repeatable engine: play a Dragon and this bounces to your hand, ready to be recast for another drain-and-dig. The catch is the cadence. Each loop asks for two mana and a Dragon, so the payoff scales with how densely you can chain them and stalls the moment the Dragon supply dries up. It is a rare case of an enchantment written to be moved rather than parked, closer in spirit to a recurring token-maker than to a static value piece. The Surveil rider is the quiet part that makes the loop worth running: because it bins cards rather than tucking them, every replay both filters toward the next Dragon and stocks the graveyard, so the engine partly feeds itself and any graveyard payoffs alongside it. Left alone it is a modest life-swing and two cards toward the yard; wired into a board that produces winged bodies on a schedule, it becomes a drip of incremental damage and card selection that grinds an opponent out two points at a time.
