Roxanne, Starfall Savant

The trigger that reads as the value engine (a tapped Meteorite on every entry and attack, two damage on arrival, a color-fixing rock) is not where the card gets scary. The scary part is the reminder that Meteorites tap for one mana of any color, and the second ability then adds a matching mana of that same type back into your pool. Every Meteorite you make effectively taps for two, and so does any other artifact token you tap for mana. Fixing that looks like a minor convenience turns into doubling, and a board of tokens becomes a mana surge instead of a slow attrition grind. The payoff scales with token count, which pushes this toward a deck already committed to going wide on artifacts rather than one that just wants a 4/3 with a ping stapled on. It occupies a spot Gruul rarely fills with a single card: repeatable reach that can be aimed anywhere (two damage per Meteorite) sitting next to explosive ramp that shrugs off color requirements. The Meteorite text itself is a bundle of hooks: sacrifice fodder for artifact aristocrats, countable bodies for token-matters payoffs, and prime material for any effect that copies a token outright before it leaves. The repeatable Meteorite damage closes games; the mana arithmetic is the real subject.
