Parallax Wave + Leonin Relic-Warder + Karmic Guide + Carrion Feeder

Parallax Wave

Leonin Relic-Warder

Karmic Guide

Carrion Feeder

How it works

1. Cast Leonin Relic-Warder by paying .
2. When Leonin Relic-Warder enters the battlefield, its first ability triggers.
3. Holding priority, activate Parallax Wave by removing a fade counter from it, exiling Karmic Guide.
4. Resolve the Leonin Relic-Warder trigger, exiling Parallax Wave.
5. When Parallax Wave leaves the battlefield, it triggers.
6. Holding priority, activate Carrion Feeder by sacrificing Leonin Relic-Warder.
7. When Leonin Relic-Warder leaves the battlefield, its second ability triggers, returning Parallax Wave from exile to the battlefield.
8. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
9. Resolve the Parallax Wave trigger from step 5, returning Karmic Guide from exile to the battlefield.
10. When Karmic Guide enters the battlefield, it triggers, returning Leonin Relic-Warder from your graveyard to the battlefield.
11. Repeat from step 2.

This intricate loop relies on Parallax Wave and Leonin Relic-Warder continuously exiling one another to trigger endless recursive entry and departure triggers. As Leonin Relic-Warder cycles in and out of play, Karmic Guide is repeatedly pulled straight from your graveyard to restart the engine every time it is sacrificed. Meanwhile, Carrion Feeder acts as the designated sacrifice outlet that fuels the whole cycle while converting every iteration into infinitely large stats.
