Untap, Upkeep, Upkeep, Upkeep, Upkeep... by Gertrude

Format: Commander

Commander: Obeka, Splitter of Seconds

Bracket: 4

Deck overview

Obeka, Splitter of Seconds is the engine and primary win condition: each point of combat damage adds an upkeep, letting the deck multiply upkeep-triggered advantages. The main plan is to run Descent into Avernus with Mechanized Production for a treasure-copy win, backed by Descent's cumulative damage and by the three Courts as alternate clocks. Secondary lines use Court of Ire/Embereth, Darksteel Reactor, and Chronozoa. The deck protects Obeka with equipment and free counters, and uses tutors to find the missing engine piece. There is no hidden commander; every route is built to reward repeated combat damage from Obeka.
