Ashaya, Soul of the Wild

Blossoming Tortoise

Spawning Pit

Xenic Poltergeist

Elspeth, Storm Slayer

How it works

1. Animate Spawning Pit using Xenic Poltergeist.
2. Activate Spawning Pit's second ability by removing two charge counters from it, creating two creature tokens.
3. Activate Spawning Pit's first ability twice by sacrificing the creature tokens, putting two charge counters on it.
4. Repeat from step 2.

This intricate loop turns your graveyard and artifacts into a self-sustaining engine, beginning with Xenic Poltergeist transforming Spawning Pit into an artifact creature so it can participate in the action. Ashaya, Soul of the Wild steps in to make your nontoken creatures into Forests—and more importantly, thanks to Blossoming Tortoise granting a cost reduction and a power boost to land creatures, that discount applies to the newly animated Spawning Pit's activation cost. Meanwhile, Elspeth, Storm Slayer doubles the creation of any tokens, ensuring that when you spend your reduced mana to remove charge counters and generate tokens, you get twice as many to feed back into Spawning Pit's sacrifice ability for infinite loops.
