Hargilde, Kindly Runechanter

Ramp that only ramps in one direction: the two colorless it makes can build an artifact spell or fuel an artifact's ability, and nothing else. That restriction is the whole point of the design. A commander whose mana is earmarked cannot accidentally become a generic accelerant, so the card only earns its slot in a deck already committed to hard artifact density, where the colorless flows straight into cost reduction, big equipment, or a mana rock that keeps the chain going. The Friends forever partner clause is what elevates it past a plain artifact enabler: it lets you pair Hargilde with any other Friends forever legend regardless of color identity, so a mono-artifact ramp piece can sit alongside a partner that supplies the actual game plan. The 2/3 body is deliberately unremarkable, a survivable tap-lander rather than a threat, because the value is meant to come from the mana it produces across many turns rather than from combat. It sits in the lineage of directed-mana producers stretching back to Lotus Petal and Grand Architect: mana that is cheaper or more plentiful precisely because you can only spend it on one thing. Hargilde takes that trade and wires it into a color-flexible pairing, where consistency of access matters more than raw quantity.
