Nim Deathmantle + Ashnod's Altar + Xu-Ifit, Osteoharmonist + Anger

Nim Deathmantle

Ashnod's Altar

Xu-Ifit, Osteoharmonist

Anger

How it works

1. Activate Ashnod's Altar by sacrificing another nontoken creature, adding CC.
2. When the creature dies, Nim Deathmantle triggers. Choose not to pay.
3. Activate Xu-Ifit by tapping it, returning a creature from your graveyard to the battlefield.
4. Activate Ashnod's Altar by sacrificing Xu-Ifit, adding CC.
5. When Xu-Ifit dies, Nim Deathmantle triggers, causing you to pay 4 to return it from your graveyard to the battlefield and attach Nim Deathmantle to it.
6. Repeat.

By using Ashnod's Altar to sacrifice creatures and generate mana, you trigger Nim Deathmantle's resurrection ability, which can be sustained to continuously cycle your graveyard. Xu-Ifit, Osteoharmonist plays a vital role by using its tap ability to pull a fallen creature card right back onto the battlefield, ensuring you always have fresh material to feed the Altar. Meanwhile, having Anger sitting safely in your graveyard—enabled passively as long as you control a Mountain—grants your entire looping army haste so they can immediately strike the moment they return.
