Krark-Clan Ironworks + Nim Deathmantle + Drivnod, Carnage Dominus + Myr Moonvessel

Krark-Clan Ironworks

Nim Deathmantle

Drivnod, Carnage Dominus

Myr Moonvessel

How it works

1. Activate Krark-Clan Ironworks by sacrificing Myr Moonvessel, adding CC.
2. When Myr Moonvessel dies, it and Nim Deathmantle triggers twice.
3. Resolve both Myr Moonvessel triggers, adding CC.
4. Resolve the first Nim Deathmantle trigger, choosing not to pay.
5. Resolve the second Nim Deathmantle trigger, causing you to pay 4 to return Myr Moonvessel from your graveyard to the battlefield, and attach Nim Deathmantle to it.
6. Repeat.

This engine transforms a humble Myr Moonvessel into an endless loop of mana and recycling, powered by the explosive sacrifice outlet of Krark-Clan Ironworks. Whenever the Myr hits the graveyard, Drivnod, Carnage Dominus steps in to double up its death trigger alongside Nim Deathmantle's resurrection ability, ensuring you always have the mana and the triggers you need. By feeding the resulting colorles mana right back into the Deathmantle's trigger requirement, you gain an unstoppable cascade of artifact sacrifices and creature returns.
