Insidious Growth V. 5.5 by AtrumUnum

Format: Commander

Commander: The Mycotyrant

Bracket: 2

Deck overview

The Mycotyrant deck is a Golgari self-mill engine that turns descends into a swarm of Fungus tokens and a growing trampling commander. The primary plan is to mill permanents early, cast The Mycotyrant on turn three, and convert each end-step descend trigger into tokens, then kill with commander damage or by sacrificing the huge Mycotyrant to Jarad. Secondary paths are Saproling drain synergies (Slimefoot, Nemata, Mirkwood Bats, Ayara) and reanimation value from Deadbridge Chant, Nyx Weaver, and Aftermath Analyst. Grist, the Hunger Tide acts as a hidden-commander-style second engine, milling, removing creatures, and finishing with its ultimate. The deck is not a combo deck; it wins through incremental board presence and graveyard recursion.
