Cloudstone Curio + Vexing Devil + Phyrexian Altar + Life Finds a Way

Cloudstone Curio

Vexing Devil

Phyrexian Altar

Life Finds a Way

How it works

1. Cast Vexing Devil by paying .
2. When Vexing Devil enters the battlefield, it, Cloudstone Curio and Life Finds a Way trigger.
3. Resolve the Cloudstone Curio trigger, doing nothing.
4. Resolve the Life Finds a Way trigger, creating a copy of any nonartifact creature token you control.
5. When the creature token enters the battlefield, Cloudstone Curio triggers, returning Vexing Devil to your hand from the battlefield.
6. Resolve the Vexing Devil trigger from sttep 2, doing nothing.
7. Activate Phyrexian Altar by sacrificing a creature token, adding .
8. Repeat.

This clever loop relies on Vexing Devil entering the battlefield to trigger Cloudstone Curio, allowing you to bounce it right back to your hand as tokens enter. The engine is fueled by Phyrexian Altar, which happily consumes the creature tokens produced along the way to generate the red mana needed to recast Vexing Devil over and over. Meanwhile, Life Finds a Way acts as the exponential heart of the setup, populating your board with fresh copies of your creature tokens whenever a big 4-power threat drops, turning a simple recursion trick into an endless cascade of triggers.
