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, Sapling Nursery triggers, creating a creature token.
Activate Ashnod's Altar by sacrificing the creature token, adding CC.
