Biophagus

A mana dork that pays a dividend on the creatures it fixes. Most one-shot ramp bodies stop at the mana: tap, add, move on. This one folds a second reward into the same activation, but only when the mana it produces goes toward a creature spell, at which point that creature shows up a little larger than it should. The design lives in that conditional. Spend the mana on a removal spell or a rock and you get nothing extra; commit it to a body and the ramp doubles as an anthem-in-miniature, one counter at a time. Keep casting creatures and the counters keep coming, which quietly steers a deck toward stacking bodies rather than teeing up one big noncreature payoff. The 1/3 frame matters here too: a three-toughness backside on a two-drop dodges the incidental sweep that clears most one-toughness accelerants, so the enhancement engine tends to survive long enough to compound. It is fixing, ramp, and a small growth engine welded into one activation, with the whole thing gated behind the requirement that you keep spending its mana on creatures to collect on it.
