Whenever Karn blocks or becomes blocked, it gets -4/+4 until end of turn.
: Target noncreature artifact becomes an artifact creature with power and toughness each equal to its mana value until end of turn.
Karn turns your noncreature artifacts (mana rocks, equipment, Stax pieces) into attacking creatures, then leverages colorless ramp and artifact synergies to grind opponents out. You ramp hard with rocks, deploy taxing artifacts, and either swing wide with animated artifacts or assemble an artifact-based combo to close.
Add fast colorless ramp (Mana Crypt, Sol Ring, Mishra's Workshop, Grim Monolith) and the Voltaic Construct + Gilded Lotus combo with Staff of Domination or Walking Ballista as payoffs. Tighten the artifact tutor package (Trinket Mage, Fabricate, Whir of Invention) and lean into either a Stax shell with Winter Orb/Tangle Wire or a streamlined combo line. Mycosynth Lattice unlocks Karn's most powerful interactions—turning all lands into animatable creatures and enabling Lattice-based locks.
