Deck overview

This deck is a Jeskai artifact midrange engine commanded by Tetzin, Gnome Champion. It leverages double-faced artifact cards from recent sets alongside classic artifact support to generate massive card advantage and board presence. In the early game, the deck ramps quickly with efficient mana rocks and cost reducers to cast Tetzin on turn 3. Tetzin turns every double-faced artifact into a self-mill and card-selection trigger, filling the graveyard while refilling the hand. In the mid-to-late game, Tetzin crafts into The Golden-Gear Colossus, transforming high-value double-faced cards for free whenever it attacks. The deck finishes games through wide combat overruns using Cyberdrive Awakener, Depthshaker Titan, massive Gnome tokens from Barracks of the Thousand, or explosive single-target damage from Kappa Cannoneer. It relies on robust passive protection from Padeem, Consul of Innovation and graveyard-fueled resilience to grind out opponents.
