Adrix and Nev, Twincasters + Nim Deathmantle + Ashnod's Altar + Prosperous Innkeeper

Adrix and Nev, Twincasters

Nim Deathmantle

Ashnod's Altar

Prosperous Innkeeper

How it works

1. Activate Ashnod's Altar by sacrificing Prosperous Innkeeper, adding CC.
2. When Prosperous Innkeeper dies, Nim Deathmantle triggers, causing you to pay 4 to return Prosperous Innkeeper from your graveyard to the battlefield, and attach Nim Deathmantle to it.
3. When Prosperous Innkeeper enters the battlefield, it triggers, creating two Treasure artifact tokens.
4. Activate the Treasures by tapping and sacrificing them, adding 2.
5. Repeat.

This loop transforms a modest halfling into a boundless engine of life and artifacts, perfectly suited for the Commander format. By leveraging Ashnod's Altar to sacrifice Prosperous Innkeeper, you generate the raw mana needed to satisfy Nim Deathmantle's revival trigger when the Innkeeper hits the graveyard. As the Innkeeper returns to the battlefield, its entry triggers the creation of a Treasure token, which Adrix and Nev, Twincasters doubles into two Treasures. Sacrificing those duplicated Treasures provides the exact mana required to fuel the Deathmantle's resurrection cost on the next iteration, all while gaining life from the Innkeeper's repeated arrivals.
