Ulamog's Dreadsire + Thornbite Staff + Ashnod's Altar

Ulamog's Dreadsire

Thornbite Staff

Ashnod's Altar

How it works

1. Activate Ulamog's Dreadsire by tapping it, creating a 10/10 Eldrazi creature tokens.
2. Activate Ashnod's Altar by sacrificing the Eldrazi token, adding CC.
3. When the Eldrazi token dies, Ulamog's Dreadsire triggers, untapping Ulamog's Dreadsire.
4. Repeat.

By equipping Thornbite Staff to Ulamog's Dreadsire, we grant the Eldrazi a lethal pinprick and a crucial untap trigger whenever any creature dies. This turns the tap ability of Ulamog's Dreadsire into a repeatable engine that spits out massive 10/10 tokens on demand. Feeding those tokens directly into Ashnod's Altar converts each death into two colorless mana, leaving enough surplus energy left over to fuel an infinite loop of creature generation, sacrifices, and mana production.
