Selesnya Toxic Blitz

A blistering Historic Selesnya Toxic deck that accelerates poison with one-drops, Venerated Rotpriest, and proliferate, then finishes with huge toxic beaters.

Venerated Rotpriest turns every creature spell into a poison counter; with 30 creatures, even one unanswered Rotpriest can kill without combat. Birds of Paradise smooths early mana, while Evolution Sage plus Evolving Wilds/Fabled Passage proliferates every land sacrifice, adding poison and +1/+1 counters. Bloated Contaminator combines toxic damage with on-combat proliferate; Skrelv and Crawling Chorus put early poison on the opponent. Tyrranax Rex is the finisher: its toxic 4 means any hit after a few poison triggers is lethal.

Keep 2-3 lands, a one-drop (Crawling Chorus, Skrelv, or Birds of Paradise), and preferably Venerated Rotpriest or Evolution Sage. Mulligan hands with 4+ lands or only Tyrranax/Collected Company.

Early: play threats every turn, put the opponent on poison immediately. Mid: use Evolution Sage and Evolving Wilds to proliferate, land Bloated Contaminator/Contagious Vorrac, and protect key creatures with Snakeskin Veil/Heroic Intervention. Late: cast Collected Company to reload, then Tyrranax Rex ends the game in one attack.

Vulnerable to board wipes and instant-speed removal on Venerated Rotpriest. Fatties with deathtouch or lifelink can stall the ground. Unclaimed Territory cannot cast noncreature spells, so mana sequencing matters. For BO3, add efficient green removal, Rest in Peace, and extra Heroic Intervention.
