MTG Combo: Animate Dead + Leonin Relic-Warder + Mayhem Devil

Relatively simple combo, requires having Mayhem Devil on the battlefield and Leonin Relic-Warder in the grave when Animate Dead enters the battlefield.

Leonin Relic-Warder and Animate Dead is an infinite loop where you target Leonin Relic Warder that's in your grave with Animate Dead, return the Leonin to the battlefield, then exile the Animate Dead that's attached to it, sacrificing the Leonin, which returns the Animate Dead back to the battlefield.

This combo generates infinite sacrifice triggers, death triggers and etb triggers. Mayhem Devil uses the infinite sac triggers to deal infinite damage to anything.
