Nim Deathmantle + Ashnod's Altar + Accomplished Automaton

Nim Deathmantle

Ashnod's Altar

Accomplished Automaton

How it works

1. Activate Ashnod's Altar by sacrificing Accomplished Automaton, adding CC.
2. When Accomplished Automaton dies, Nim Deathmantle triggers, causing you to pay 4 to return Accomplished Automaton from your graveyard to the battlefield, and attach Nim Deathmantle to it.
3. When Accomplished Automaton enters the battlefield, its fabricate ability triggers, creating a 1/1 Servo artifact creature token.
4. Activate Ashnod's Altar by sacrificing the Servo, adding CC.
5. Repeat.

This clever loop turns the mechanical heavy lifting of Accomplished Automaton into an endless self-sustaining engine. By feeding both the automaton and the token it creates through Ashnod's Altar, you generate the exact amount of mana required to fund Nim Deathmantle’s resurrection trigger. Each cycle refreshes your sacrificial fuel while netting you an infinite stream of triggers, proving that even a humble automaton has plenty of mechanical utility left to give.
