Memnarch, the Warden is a colorless artifact ramp deck. It floods the board with mana rocks, cost reducers and artifact creatures so the 10-mana commander lands early, then turns each Memnarch attack into a huge card draw, one card per artifact. Big mana from Tron lands, untappers and doubling effects also powers out colorless bombs and Ugin planeswalkers. Most of the colored world gets swept away while the artifact board survives. How it wins: Massive artifact boards go wide and tall, with Memnarch and big constructs swinging behind evasion and anthem effects, and colorless value loops like Glaring Fleshraker with Sensei's Divining Top and Mystic Forge can finish the game outright. Key roles: - Explosive colorless mana: Fast rocks, big-mana lands and untap effects let the deck cast Memnarch and nine-drops turns ahead of schedule, and some doubling stacks on top of the artifact count (Basalt Monolith, Voltaic Key, Forsaken Monument) - Artifact cost reduction: Affinity, improvise and discount effects scale with the artifact count, turning a wide board into nearly free threats (Mycosynth Golem, Metalwork Colossus, Darksteel Monolith) - Artifact-count payoffs: Memnarch's attack draws, the Battlesphere's Myr damage and equipment that grows with artifacts all reward keeping many artifacts in play (Myr Battlesphere, Nettlecyst, Steel Overseer) - Sacrifice and recursion loops: Artifacts get sacrificed for mana or tutors and returned from the graveyard. With Glaring Fleshraker pinging on every recast, this becomes an infinite damage engine (Krark-Clan Ironworks, Scrap Trawler, Myr Retriever) - Colorless spell chains: Casting colorless spells from the top of the library or copying them makes Spawn tokens and damage triggers that can go infinite (Mystic Forge, Sensei's Divining Top, Echoes of Eternity) - Colorless sweepers and team evasion: One-sided wipes of colored permanents clear blockers while the artifact army gains flying, haste and indestructibility to close the game (All Is Dust, Ugin, Eye of the Storms, Krang, Utrom Warlord)
