The Mycotyrant + Morality Shift + Mayael's Aria

The Mycotyrant

Morality Shift

Mayael's Aria

How it works

1. Cast Morality Shift by paying 5, exchanging your graveyard and library, causing you to descend once for each permanent card put into your graveyard this way.
2. At the beginning of your end step, The Mycotyrant triggers, creating a number of 1/1 Fungus creature tokens equal to the number of times you've descended this turn.
3. At the beginning of your next upkeep, Mayael's Aria triggers, causing you to put a +1/+1 counter on each creature you control, gain 10 life and win the game.

This fascinating sequence turns a massive graveyard dump into an instant win by weaving together three distinct permanent effects. First, casting Morality Shift dumps your entire library into your graveyard, triggering The Mycotyrant a massive number of times—and since you descended for every permanent card that hit the bin, The Mycotyrant creates an army of Fungus tokens at your end step while also growing to a gargantuan size thanks to its own Fungi and Saprolings scaling. When your next turn rolls around, Mayael's Aria immediately checks your board state during your upkeep, capitalizing on The Mycotyrant's newly inflated power to effortlessly clear the 20-power threshold and secure the game on the spot.
