Nim Deathmantle + Ashnod's Altar + Stone-Giant of High Pass

Nim Deathmantle

Ashnod's Altar

Stone-Giant of High Pass

How it works

1. Activate Ashnod's Altar by sacrificing Stone-Giant of High Pass, adding CC.
2. When Stone-Giant of High Pass dies, Nim Deathmantle triggers, causing you to pay 4 to return Stone-Giant of High Pass from your graveyard to the battlefield and attach Nim Deathmantle to it.
3. When Stone-Giant of High Pass enters, it triggers, creating a creature token.
4. Activate Ashnod's Altar by sacrificing a creature token, adding CC.
5. Repeat.
