Sanctum Weaver

The lineage of enchantment-payoff mana producers reaches back to Serra's Sanctum, but that idea gets compressed here into a two-drop that scales with a board green enchantment decks were already assembling for other reasons. Because it is itself an enchantment, it counts itself: on an empty board X is one, so early on it produces exactly one mana of your chosen color and serves as a passable turn-two accelerant. Output climbs one per enchantment, a linear ramp that becomes dangerous less because any single tap grows fast and more because enchantment-dense shells pile up density quickly. Every aura, saga, or enchantment creature you resolve raises the ceiling on all future activations, so infrastructure the deck wanted anyway converts a slow build into one explosive tap. The quiet restriction is "any one color": you get raw quantity, potentially absurd quantity, but you lock into a single color the instant you tap it. That makes it a fuel line for a big monocolored spell rather than a smoother for a greedy manabase, which separates it from the color-correction offered by Cryptolith Rite or Sylvan Caryatid. This is a burst engine, not a fixing tool. The 0/2 body leaves it fragile to any removal and reinforces that its worth is entirely off-board, tethered to the enchantments surrounding it. A modest one-color trickle at first, it becomes, a few permanents later, the kind of activation that ends a turn by itself.
