How it works
Activate Ashnod's Altar by sacrificing Ashaya, adding CC.
When Ashaya dies, Nim Deathmantle triggers, causing you to pay 4 to return Dryad Arbor from your graveyard to the battlefield, and attaching Nim Deathmantle to it.
When Ashaya enters the battlefield, Thranduil triggers, creating a creature token.
Activate Ashnod's Altar by sacrificing the creature token, adding CC.
Repeat.
If you control a nontoken creature that has haste, you may instead sacrifice it, and then tap it each iteration to get infinite green mana and colorless mana.
