Up Your Keep by TsulKalu

Format: Commander

Commander: Obeka, Splitter of Seconds

Bracket: 3

Deck overview

Grixis upkeep-machine deck built around Obeka, Splitter of Seconds: Obeka turns a single unblocked hit into a burst of extra upkeep steps, letting a suite of upkeep triggers snowball. The primary finish is combat damage generating enough extra upkeeps for Mechanized Production to copy a Treasure token up to eight copies and win, with Darksteel Reactor as a parallel counter-based win. Backup plans drain opponents with Creeping Bloodsucker, Stormfist Crusader, Scrawling Crawler, and Twilight Prophet, while The Scarab God and reanimation spells provide a long-game engine. Obeka is the key acceleration piece; the deck can grind without her but loses most of its velocity.
