Janky Fynn Poison

A janky green poison deck that uses Fynn, the Fangbearer and Saryth, the Viper’s Fang to turn small creatures into deathtouch threats, rapidly accumulating poison counters while protecting the board with Heroic Intervention and pump spells.

Saryth grants deathtouch to all tapped creatures, so every attacker—even mana dorks—can trigger Fynn’s ability to give two poison counters per hit. Venerated Rotpriest’s replacement effect adds an extra poison counter whenever an opponent would get one, multiplying the output from both toxic and Fynn triggers. Mosswood Dreadknight and Scavenging Ooze apply early pressure, while Questing Beast punches through blockers. Toski draws cards on each hit to keep the hand full. Primal Might and Inscription of Abundance double as removal and pump, often targeting a creature to trigger Rotpriest’s counter bonus if that creature also deals combat damage.

Keep hands with two or three lands, a 1‑drop (Llanowar Elves or Rotpriest), and either Fynn or Saryth. A hand with protection or pump spells and at least two creatures is keepable. Mulligan if you lack early plays or have no way to apply poison pressure before turn three.

Early turns: deploy Elves and Rotpriest; drop Fynn on turn two to start attacking immediately with deathtouch from Rotpriest or Dreadknight. Midgame: deploy Saryth to blanket your board with deathtouch, then swing with multiple creatures to stack poison. Use Heroic Intervention to guard against sweepers. Late game: a wide board of deathtouchers and Toski drawing cards overwhelms the opponent; Questing Beast or a pumped attacker finishes the game with a lethal poison total.

Spot removal on Saryth or Fynn disrupts the poison engine; without deathtouch, poison output plummets. Board wipes are dangerous if Intervention isn’t available. The deck is weak to flying and trample, as it has few blockers with reach. Faster combo decks can race before poison stacks up.
