Ashaya, Soul of the Wild + Blossoming Tortoise + Spawning Pit + March of the Machines + Bard, King of Dale

Ashaya, Soul of the Wild

Blossoming Tortoise

Spawning Pit

March of the Machines

Bard, King of Dale

How it works

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

This brilliant looping engine transforms simple artifact sacrifice into an endless cascade of creature tokens by weaving together static buffs and replacement effects. With March of the Machines turning Spawning Pit into an artifact creature, and Ashaya, Soul of the Wild simultaneously making all your nontoken creatures into Forest lands, every piece of the puzzle interacts seamlessly. Blossoming Tortoise helps set the graveyard while pumping your land creatures and discounting land abilities, though the real magic happens when Bard, King of Dale doubles the token output of Spawning Pit. You simply sacrifice the spawned creatures right back to the Spawning Pit to refill its charge counters, generating infinite sacrifice and death triggers in the process.
