Stonespeaker Crystal

Colorless mana rocks are a dime a dozen, and colorless graveyard hate is nearly as common; what this bolts together is the recognition that both jobs sit idle most of the game. A rock that only ever taps for two colorless mana is a slot most decks can find room for but rarely feel good about, and dedicated graveyard exile is a card you desperately want in exactly one matchup and would happily cut in every other. Stapling the second onto the first solves the dead-card problem from both ends: the crystal earns its keep as ramp until the turn the graveyard war matters, then converts itself into a wide exile plus a replacement draw, so cashing it in leaves your hand no lighter than it started. The exile clause reaches any number of target players' graveyards, so it scales from a scalpel against a single reanimator opponent to a table-wide reset when several decks are leaning on their bins. That range is what recommends a colorless answer over a color-committed one: it makes no demand on a manabase and belongs anywhere, whatever the deck's colors. The quieter design lesson is that a mana source able to retire itself for value is fundamentally more attractive than one that just sits there, because it never becomes the topdeck you wish had been anything else.
