Ruby Medallion card art
Ruby Medallion shears one generic mana off every red spell you cast — in a spell-heavy deck, that's effectively two or three free spells over a game. At two mana with no ongoing cost, it pays for itself the turn you chain a Reiterate or watch Lorehold, the Historian fire off a string of instant-speed triggers.

Best Commanders

Commanders with the highest synergy

01
Lorehold, the Historian

Lorehold, the Historian

42.9% of decks · synergy 0.37

Lorehold, the Historian churns through instants and sorceries at volume, and Ruby Medallion turns that volume into tempo — each discounted spell is another trigger closer to an overwhelming board state.

02
Niv-Mizzet, Visionary

Niv-Mizzet, Visionary

41.9% of decks · synergy 0.32

Niv-Mizzet, Visionary wants to cast as many spells as possible to stack its multicolor payoffs, and Ruby Medallion makes every red spell in that chain cost one less, stretching a single turn's mana into two or three extra casts.

03

Kuja, Genome Sorcerer

39.1% of decks · synergy 0.28

Kuja, Genome Sorcerer leans on a high density of red spells to generate value, and Ruby Medallion shaves enough mana across a turn to push Kuja's engine from good to threatening.

04

Ral, Monsoon Mage

38.6% of decks · synergy 0.28

Ral, Monsoon Mage flips on the back of casting instants and sorceries in rapid succession, and Ruby Medallion makes each red spell cheaper so you can string together the triggers needed to flip him in a single turn.

05
Ashling, Flame Dancer

Ashling, Flame Dancer

80.4% of decks · synergy 0.25

Ashling, Flame Dancer triggers on every noncreature red spell, so Ruby Medallion's discount directly translates to more spells cast per turn and more counters stacked on Ashling.

Commander is where Ruby Medallion earns its slot — red spell-slinger decks run it at high rates precisely because the discount compounds across a 100-card, four-player game where you're casting spells every turn for an hour. In Legacy and Vintage it's technically legal but almost never played; those formats move too fast for a two-mana artifact that doesn't affect the board immediately, and dedicated red strategies there would rather play rituals. Oathbreaker is a reasonable home for the same reasons as Commander — smaller deck, faster games, but the cost reduction still matters in spell-dense builds.

Budget Alternatives

Cheaper options that do most of the same work

Hazoret's Monument does most of the same work in mono-red or red-heavy creature decks, shaving one mana off red creature spells and tacking on a loot trigger for three mana — the extra cost and the creature-only restriction are real trade-offs against Ruby Medallion's universal discount. If your red spells lean heavily toward the four-plus mana range, Fire Diamond gives you one mana of acceleration for two mana, though it enters tapped and doesn't scale the way a flat cost reduction does across a full game.

Price Context

Current price

$12.18 mid tier

At $12.18, Ruby Medallion sits in the mid tier — not a casual pickup, but firmly justified in any red spell-heavy Commander deck where it will trigger multiple times per game. It's a perennial reprint target, so prices tend to soften after new editions, but at this price it's already reasonable for the power level it delivers.
