Karn, Gilded Guardian Commander Deck Guide (Reality Fracture)

Karn, Gilded Guardian is a five-color artifact payoff you can slot into almost anything — its hybrid cost lets you cast it with generic mana, but naming it a five-color commander unlocks the whole artifact toolbox. Here's the build.

Reading the Commander

Karn costs {2/W}{2/U}{2/B}{2/R}{2/G} — each pip can be paid with two generic mana or one mana of that color, so you can hard-cast him for ten generic in any deck. As a commander he's five-color (his color identity spans WUBRG). He's a vigilance, trample Golem, and:

• - When Karn enters, draw a card for each color among other artifacts you control.

Run colored mana rocks and multicolor artifacts and his ETB refills your hand.

The Game Plan

You're a five-color artifacts goodstuff deck: ramp on rocks, deploy powerful artifacts across all colors, and use Karn as a resilient beater that pays you off in cards. Five colors means you can play the best artifact and colorless staples in the game with no restriction.

Core Package

• - Colored mana rocks (Signets, Talismans, the five "colored" rocks) to maximise Karn's ETB card count and fix your mana.
• - Artifact payoffs: Urza, Karn's Bastion, Unwinding Clock, artifact-matters anthems, and cost reducers.
• - Colorless / artifact staples: the format's best artifacts, unrestricted by color.
• - Reality Fracture synergy: Memnarch, the Warden and other new artifact cards; Craterclaw Colossus as a trample finisher.

The Skeleton

Build to the Commander template, tuned five-color artifacts:

• - 1 Karn, Gilded Guardian
• - 35–37 lands + heavy artifact ramp
• - 12+ ramp — colored rocks pull double duty as Karn fuel and fixing
• - 9 removal + 3 board wipes
• - 10+ artifact payoffs and value engines
• - 2–3 win conditions

Mana Base Notes

Five colors sounds scary, but an artifact deck fixes itself: 12+ mana rocks plus rainbow lands make WUBRG trivial. Prioritise rocks over lands here. See the mana base guide.

How You Win

Grind value off artifacts and Karn's ETB, then close with a big artifact finisher, an Urza-style engine, or Craterclaw Colossus handing the team trample. Keep a clear win condition in the list.
