Commander: Obeka, Splitter of Seconds

Bracket: 3

Deck overview

This deck leverages Obeka, Splitter of Seconds to turn combat damage into massive value through additional upkeep steps. By deploying powerful upkeep-triggered permanents, the Court monarch cycle, and suspend spells, each unblocked attack accelerates board development, resource generation, and direct damage exponentially. The primary plan involves ensuring Obeka connects using evasion equipment and auras, multiplying upkeep triggers to drain life totals with cards like Court of Ambition and Twilight Prophet. Alternative win conditions include infinite combats with Aggravated Assault and Sword of Feast and Famine, or generating eight matching artifact tokens with Mechanized Production.
