Deck overview

This deck is a mono-green poison aggro and proliferate deck commanded by Fynn, the Fangbearer. The primary strategy focuses on deploying low-mana deathtouch creatures early, casting Fynn on Turn 2, and attacking opponents to rapidly assign two poison counters per unblocked strike. Because poison requires only ten counters per player to eliminate an opponent, the deck bypasses normal 40-life totals entirely. Mid-game turns scale the poison clock using proliferate engines such as Evolution Sage, Contaminant Grafter, and Sword of Truth and Justice, alongside counter doublers like Vorinclex, Monstrous Raider and Innkeeper's Talent. The deck can also close games through burst overruns using Triumph of the Hordes or Finale of Devastation. While the deck features explosive early speed and high combat lethality, it relies on maintaining creature presence on board. It protects its assets with Heroic Intervention and Veil of Summer while leveraging versatile removal to break through opposing blockers.
