Legendary Artifact Creature — Golem
Karn's power and toughness are each equal to the greatest mana value among artifacts you control. At the beginning of your upkeep, add {C} for each artifact you control. This mana can't be spent to cast nonartifact spells. Until end of turn, you don't lose this mana as steps and phases end.
“Grow a colorless golem by flooding the board with cheap artifacts and mana”
Karn, Legacy Reforged is an artifact-focused commander that turns your artifact count into a growing threat. Your core gameplan is simple: build a dense artifact board, use Karn as a mana engine that fuels more artifacts, and watch it grow bigger while generating the mana to cast more threats. The deck wants to snowball—early ramp into cheap artifacts, then chain-cast bigger ones powered by Karn's mana generation. Your artifacts effectively become free as the game progresses, letting you vomit out threats while Karn beats down as an oversized flyer.
The beauty is that Karn doesn't ask for much deck building contortion. Colorless artifacts naturally synergize with artifact synergies: token makers like Myriad Construct, draw engines like Jhoira's Familiar, and sacrifice outlets for additional value. You'll often win through sheer board pressure—Karn + a bunch of artifact tokens is hard to race. Some builds lean into artifact-specific synergies like Aetherflux Reservoir or Lattice-style effects, but the straightforward path is just casting more stuff than your opponents can handle.

Skip pricey rocks like Mox Opal; use Everflowing Chalice, Azorius Signet, and colorless mana dorks like Axebane Guardian instead. Cheaper artifact tokens come from Servo Schematic and Emry staples.
