How it works
Activate Ashnod's Altar by sacrificing HYDRA Troopers, adding CC.
When HYDRA Troopers dies, Nim Deathmantle triggers, causing you to pay 4 to return HYDRA Troopers from your graveyard to the battlefield and attach Nim Deathmantle to it.
When HYDRA Troopers enters, it triggers, creating a creature token.
Activate Ashnod's Altar by sacrificing a creature token, adding CC.
