Nim Deathmantle + Ashnod's Altar + Glint-Sleeve Artisan

Nim Deathmantle

Ashnod's Altar

Glint-Sleeve Artisan

How it works

1. Activate Ashnod's Altar by sacrificing Glint-Sleeve Artisan, adding CC.
2. When Glint-Sleeve Artisan dies, Nim Deathmantle triggers, causing you to pay 4 to return Glint-Sleeve Artisan from your graveyard to the battlefield, and attach Nim Deathmantle to it.
3. When Glint-Sleeve Artisan 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 standard artisan work into an endless engine by using Ashnod's Altar to sacrifice Glint-Sleeve Artisan for two colorless mana. When Glint-Sleeve Artisan hits the graveyard, Nim Deathmantle's triggered ability steps in, allowing you to pay four mana to return the Artisan straight to the battlefield equipped and ready to go. The key to sustaining this mana-wise is the Artisan's own fabricate 1 ability, which creates a Servo artifact creature token upon entry. Sacrificing that freshly minted Servo to Ashnod's Altar provides the exact remaining mana needed to fund the Deathmantle's resurrection fee, generating an infinite loop of sacrifices, entries, and death triggers.
