Nim Deathmantle + Ashnod's Altar + Thorin, Mountain-king + Sporeweb Weaver

Nim Deathmantle

Ashnod's Altar

Thorin, Mountain-king

Sporeweb Weaver

How it works

1. Activate Ashnod's Altar by sacrificing Thorin, adding CC.
2. When Thorin dies, Nim Deathmantle triggers, causing you to pay 4 to return Thorin from your graveyard to the battlefield and attach Nim Deathmantle to it.
3. When Thorin enters, it triggers, attaching Nim Deathmantle to Sporeweb Weaver, and then having it deal damage to itself.
4. Sporeweb Weaver triggers, creating a creature token and causing you to gain 1 life
5. Activate Ashnod's Altar by sacrificing the creature token, adding CC.
6. Repeat.
