Ashaya, Soul of the Wild + Blossoming Tortoise + Misery's Shadow

Ashaya, Soul of the Wild

Blossoming Tortoise

Misery's Shadow

How it works

1. Activate Misery's Shadow by paying 0 due to Blossoming Tortoise, giving Misery's Shadow +1/+1 until end of turn.
2. Repeat.

This loop transforms Misery's Shadow into an infinitely massive threat by exploiting the synergy between Ashaya, Soul of the Wild and Blossoming Tortoise. Because Ashaya turns all your nontoken creatures into Forest lands in addition to their other types, Misery's Shadow is treated as a land—allowing Blossoming Tortoise to slash its activation cost by {1}. With that cost reduction dropping the ability's price from {1} down to zero, you can pump Misery's Shadow infinitely to create a game-ending attacker out of nowhere.
