Nim Deathmantle + Ashnod's Altar + Woe Strider

Nim Deathmantle

Ashnod's Altar

Woe Strider

How it works

1. Activate Ashnod's Altar by sacrificing Woe Strider, adding CC.
2. When Woe Strider dies, Nim Deathmantle triggers, causing you to pay 4 to return Woe Strider from your graveyard to the battlefield and attach Nim Deathmantle to it.
3. When Woe Strider enters, it triggers, creating a creature token.
4. Activate Ashnod's Altar by sacrificing a creature token, adding CC.
5. Repeat.

This loop relies on a brilliant self-sustaining cycle of sacrifice and resurrection, fueled by Nim Deathmantle's ability to pull a fallen creature right back to the battlefield. Whenever Woe Strider is fed to Ashnod's Altar, the two colorless mana generated by the sacrifice provides the exact half of the four-mana fee required by the Deathmantle, leaving you just two mana short until you factor in the additional creature. Thankfully, Woe Strider’s entry brings along a loyal Goat token to be sacrificed to Ashnod's Altar as well, supplying the remaining mana needed to pay the Deathmantle's revival cost and perpetuate the cycle indefinitely.
