Prize Pig

Most mana dorks pay for their fixing with a body you never plan to attack with; this one adds a second toll and a second reward, turning incidental lifegain into an untap. The ribbon counters are a meter: each point of life you gain stacks one, and the instant three or more sit on the Boar, the whole pile clears and it untaps for another mana of any color. That reroutes an axis green already brushes against (lifegain) into the axis green wants most (mana), without asking you to splash. The governor is the threshold. A trickle of one or two life does nothing until it compounds, so the card wants either steady incremental gain or a single meaningful swing rather than one stray point. The clearing clause is where the design shows its restraint: because all counters come off at once when you cross three, a lump of six life untaps the creature exactly once, not twice. Bulk lifegain does not chain the untap; only a sequence of separate triggers, each pushing the total past three again, produces multiple untaps in a turn. So the payoff scales with how often you gain, not how much at a time, and the 0/3 body confirms the assignment: sit back, convert, and let a steady drip of life become repeated fixing. Left alone, it is a two-mana any-color dork that happens to accumulate counters; fed a source of frequent small gains, it becomes a genuine mana engine.
