Living Brain, Mechanical Marvel

Gameplan

Living Brain leads a colorless artifact deck that floods the board with mana rocks, mana batteries, and utility artifacts, then animates one each combat to swing as a 3/3 (untapping it so you can attack and still use it). You ramp hard with artifact mana, deploy a wide artifact base, and grind value until you can either go wide with animation effects, Voltron-equip the animated rock, or assemble an artifact combo finish.

Key Cards

• Karn, the Great Creator — Locks opponents out of activated artifact abilities and tutors any artifact from outside the game in colorless.
• Voltaic Construct — Untaps creatures for mana, comboing with high-output rocks animated by Living Brain for infinite mana.
• Mishra's Bauble — Cheap artifact that becomes a free 3/3 attacker and replaces itself, exemplifying the animate-anything plan.
• Walking Ballista — Colorless artifact that scales as a creature and serves as a mana-sink win condition.
• Unwinding Clock — Untaps your artifacts each turn, enabling repeated activations and pseudo-vigilance on animated rocks.

Upgrade Path

Add fast colorless ramp (Sol Ring, Mana Crypt, Mana Vault, Grim Monolith) and untap engines (Voltaic Construct, Unwinding Clock) to enable combo turns. Lean on Karn, the Great Creator plus a wishboard of silver bullets, and include Walking Ballista or an Eldrazi titan as a closer. Round out with artifact tutors like Whir of Invention—wait, colorless only—so use Planar Bridge, Reshape via Trophy Mage substitutes, and Trinket/Trinisphere stax to protect your engine.
