Karametra's Acolyte

Most mana dorks scale with nothing: a Llanowar Elves taps for one whether it is turn two or turn twelve. This one reads the board instead, paying out green for every green pip across your permanents, which turns your board's color commitment into a ramp engine. The body is the tell: a 1/4 that survives the early game and contributes almost nothing to the count it cares about, since it adds only one green symbol of its own. The trade is deliberate. To make this acolyte produce real mana you have to commit to a heavily green-pipped board first, which means it ramps best exactly when you already have a board worth ramping from, and produces a trickle when you are behind. That is the inversion that makes it a build-around rather than a generic accelerant: it is a mana doubler gated behind the same devotion currency that powers gods. Lean far enough into multi-green permanents and the tap can outpace any fixed-output dork; play it in a two-color shell with colorless and off-color costs and it stays a 1/4 that taps for one or two. The card does not reward casting it early so much as it rewards having earned a green-saturated battlefield, and it asks you to build toward that saturation deliberately.
