How it works
Activate Ashnod's Altar by sacrificing another nontoken Dragon, adding CC.
The Dragon dies, triggering Nim Deathmantle, causing you to pay 4 to return the Dragon from your graveyard to the battlefield, and attach Nim Deathmantle to it.
The Dragon enters the battlefield, triggering Lathliss, creating a 5/5 Dragon creature token.
Activate Ashnod's Altar by sacrificing the Dragon token, adding CC.
