This is a five-color artifact value deck built around repeatedly re-triggering Karn's enter-the-battlefield card draw. It packs colored and all-colored artifacts so Karn draws up to five cards each time, then blinks and doubles Karn and other enter-the-battlefield creatures. A cheap artifact mana base and cost reducers flood the board, and that board becomes an artifact army that overwhelms opponents in combat or drains them through card draw. How it wins: It buries opponents in card advantage, then closes with a large board of artifact creatures and scaling Constructs, backed by life drain from every card drawn. Key roles: - Color density for Karn: Karn only counts colors among other artifacts, so all-color effects and colored artifact creatures turn each Karn entry into a draw of four or five cards. (Leyline of the Guildpact, Sphinx of the Guildpact, Transguild Courier) - Blink and trigger doubling: Instant and repeatable flicker effects reset Karn and the gearhulk-style creatures, while doublers make every entry count twice for huge refills. (Deadeye Navigator, Ephemerate, Panharmonicon) - Artifact ramp and cost reduction: Two-mana rocks fix all five colors and inflate the artifact count, while reducers and artifact-only mana make Karn's colored hybrid cost and the expensive artifacts cheap to deploy. (Karn, Legacy Reforged, Etherium Sculptor, Talisman of Progress) - Enter-the-battlefield interaction: Artifact creatures that remove or tuck threats or recast spent instants pull double duty when blinked, copied or doubled, keeping the board clear while adding bodies. (Riptide Gearhulk, Noxious Gearhulk, Torrential Gearhulk) - Artifact army and finishers: Cast triggers churn out flying tokens, and Constructs and other creatures scale with artifact count. Mass-animation effects can turn a pile of rocks into lethal attackers. (Urza, Chief Artificer, Bronze Guardian, Rise and Shine) - Draw-to-damage: Karn's big draws and the incidental draw engines each make opponents lose life, turning card advantage directly into a win condition. (Psychosis Crawler, Losheel, Clockwork Scholar, Shimmer Dragon)
