Rainbow Slivers by BigPopo

Format: Commander

Commander: Morophon, the Boundless

Bracket: 3

Deck overview

This deck is an explosive five-color tribal build that uses Morophon, the Boundless to discount costs and assemble an unstoppable swarm of Slivers. The primary game plan establishes mana ramp through mana-producing Slivers and color fixers, followed by deploying Morophon alongside cost modifiers like Fist of Suns or Jodah, Archmage Eternal to cast Sliver spells for free. From there, legendary Slivers like The First Sliver, Sliver Overlord, and Sliver Legion flood the battlefield, grant layered abilities, and pump the entire swarm. Evasion from Cloudshredder Sliver, Shifting Sliver, and Shadow Sliver allows the deck to close out games through massive, multi-opponent combat damage.
