Krark-Clan Ironworks + Nim Deathmantle + Teysa Karlov + Myr Moonvessel

Krark-Clan Ironworks

Nim Deathmantle

Teysa Karlov

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 clever loop turns the humble Myr Moonvessel into an engine for infinite resources, perfectly orchestrated by the sacrifice engine Krark-Clan Ironworks. Because Myr Moonvessel generates mana both when it dies and through its sacrifice, it funds a portion of the recovery process, while Teysa Karlov doubles the death-triggered abilities to ensure Nim Deathmantle's resurrection trigger can find the exact opening it needs. By repeatedly cycling the creature in and out of the graveyard, you achieve infinite creature sacrifice, entry, and death triggers to overwhelm your opponents.
