Rootcoil Creeper

Most mana dorks want you to spend the mana now, the turn after the body arrives. This one is built for the second life of your cards. The any-color tap is table stakes; the design lives in the two abilities that mine a graveyard rather than let it sit inert. The double-mana mode is walled off to casting from the yard, which reads restrictive until you notice it turns every flashback spell into something you can afford twice as fast. And the exile-to-recur ability quietly solves the one problem flashback never could: a card cast from the graveyard is normally gone for good, exiled by the flashback clause itself. Pulling that card back out of exile and into your hand hands you a third cast on something the rules had already retired. That is the tension worth sitting with: a body that exists to fuel recursion engines it cannot run alone, an accelerant tuned for value across turns rather than tempo on curve. The 2/2 for two is almost incidental, a chassis to hang an any-color tap plus two narrow, deliberately self-referential abilities on. It rewards a deck full of flashback spells to feed the loop, though it still ramps just fine in a deck that has nothing in its yard worth revisiting.
