Mana Rock

Mana-producing artifacts that stick around and tap for mana each turn, the artifact backbone of ramp decks. Sol Ring and Mana Crypt accelerate explosively from turn one, while Arcane Signet, Fellwar Stone, and Gilded Lotus fix colors and add extra mana every turn. Palladium Myr counts too, since an artifact creature that taps for mana behaves as one. Distinct from Fast Mana, which sacrifices itself for a one-time mana burst rather than tapping repeatedly, and from Mana Dork, which produces the same effect on a creature body rather than an artifact. Also separate from Ritual, the one-shot instants and sorceries that vanish after a single burst.
