Nim Deathmantle + Ashnod's Altar + Ashaya, Soul of the Wild + Thranduil the Strategist

Nim Deathmantle

Ashnod's Altar

Ashaya, Soul of the Wild

Thranduil the Strategist

How it works

1. Activate Ashnod's Altar by sacrificing Ashaya, adding CC.
2. When Ashaya dies, Nim Deathmantle triggers, causing you to pay 4 to return Dryad Arbor from your graveyard to the battlefield, and attaching Nim Deathmantle to it.
3. When Ashaya enters the battlefield, Thranduil the Strategist triggers, creating a creature token.
4. Activate Ashnod's Altar by sacrificing the creature token, adding CC.
5. Repeat.
6. If you control a nontoken creature that has haste, you may instead sacrifice it, and then tap it each iteration to get infinite green mana and colorless mana.

This clever loop turns your entire board into an engine of continuous rebirth, anchored by Nim Deathmantle's ability to resurrect fallen nontoken creatures for four mana. Ashnod's Altar provides the initial sacrifice outlet and the colorless mana needed to fuel the Deathmantle's revival cost. Meanwhile, Ashaya, Soul of the Wild fundamentally alters the rules of engagement by turning all your nontoken creatures into lands, meaning any creature you sacrifice also counts as a land entering the battlefield to trigger Thranduil the Strategist. Thranduil rewards each of these landfalls by generating a fresh 1/1 green Elf creature token, which you can then feed back into Ashnod's Altar to keep the cycle spinning infinitely.
