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