Adric, Mathematical Genius card art
Adric, Mathematical Genius doubles every noncombat damage your opponents deal to each other, turning political damage into an explosive force multiplier without you lifting a finger. The catch is the same thing that makes him powerful — you're dependent on your opponents attacking each other, so tables that focus-fire you or play combo-heavy strategies leave Adric, Mathematical Genius looking for work. The Fifth Doctor and The Celestial Toymaker shells lean into this most naturally, pairing his passive with effects that encourage or force combat between opponents.

The Celestial Toymaker runs Adric, Mathematical Genius because the commander's game-forcing effects push opponents into situations where they're dealing damage to each other constantly — and Adric doubles every point of that, turning the Toymaker's chaos engine into a lethal math problem for anyone at the table.

Commander is where Adric, Mathematical Genius belongs — a four-player table means noncombat damage is flying in multiple directions at once, and his doubling trigger scales with the number of opponents dealing damage to each other. In Legacy and Vintage he's legal but effectively unplayable; those formats don't support a four-mana do-nothing-immediately creature that depends on opponents hitting each other. Oathbreaker has the same multiplayer dynamic as Commander, so he has theoretical homes there too, but the 20-life starting total compresses games before his passive generates enough value.

Price Context

Current price

$1.52 cheap tier

At $1.52, Adric, Mathematical Genius sits firmly in budget territory — easy to pick up as a rolePlayer in any Doctor Who or group-slug shell without thinking twice. Demand is niche enough that the price is unlikely to spike absent a new combo discovery, so this is a stable buy-and-forget acquisition.
