Deck overview

This deck is a focused Simic stompy and +1/+1 counter engine commanded by Primo, the Unbounded. The strategy accelerates mana on early turns to cast Primo or massive hydras with base power 0/0. Whenever these modified base-0 creatures deal combat damage, Primo triggers to create exponentially larger Fractal tokens. Supported by premier counter multipliers like Branching Evolution, Doubling Season, and Kalonian Hydra, the board scales out of reach within a couple of attack steps. While the deck relies primarily on combat damage and natural card flow, it includes resilient protection options such as Ripples of Potential and Mutational Advantage to guard against board wipes. Alternate win conditions like Simic Ascendancy and massive single-card threats like Body of Research ensure the deck can close games efficiently even if the commander is removed.
