Deck overview

This deck is a Phyrexian-themed infect/proliferate strategy helmed by Yuna, Grand Summoner, who provides mana acceleration and a +1/+1 counter boost on the next creature spell. The primary win condition is poisoning all opponents to 10 poison counters using a mix of infect and toxic creatures (Glistener Elf, Blighted Agent, Venerated Rotpriest, etc.) alongside a dense proliferate engine (Evolution Sage, Thrummingbird, Tekuthal, Inquiry Dominus, Innkeeper's Talent). The deck accelerates poison accumulation by spreading counters through combat damage and proliferate triggers, often finishing via repeated proliferate loops or unblockable infect creatures. Secondary win conditions include combat damage from large, counter-enhanced creatures (Champion of Lambholt, Herald of Secret Streams). The deck runs a solid interaction suite of counterspells, spot removal, and protection to shield its key pieces.
