Deck overview

This deck is a Simic Big Mana and Token Swarm strategy built around Koma, Cosmos Serpent. Its main goal is to accelerate rapidly through a dense suite of 1- and 2-CMC ramp spells, deploying Koma ahead of curve on Turn 4 or 5. Once on the battlefield, Koma generates a 3/3 Serpent token during every player's upkeep, rapidly building a massive board presence while using Serpent sacrifices to neutralize enemy threats and protect itself. The deck magnifies this engine through non-legendary clone effects like Spark Double and Sakashima of a Thousand Faces, alongside token doublers and tribe-wide buff effects such as Coat of Arms and Archetype of Imagination. With efficient counterspells and removal backing up its game plan, the deck converts token generation into an overwhelming combat finish by Turn 7.
