Sidisi, Regent of the Mire + Karmic Guide + Carrion Feeder + Giant-Sized Flying Ant

Sidisi, Regent of the Mire

Karmic Guide

Carrion Feeder

Giant-Sized Flying Ant

How it works

1. Activate Sidisi by tapping it and sacrificing Giant-Sized Flying Ant, returning Karmic Guide from your graveyard to the battlefield.
2. When Karmic Guide enters the battlefield, it triggers, returning Giant-Sized Flying Ant from your graveyard to the battlefield.
3. When Giant-Sized Flying Ant enters the battlefield, it triggers, untapping Sidisi.
4. Activate Carrion Feeder by sacrificing Karmic Guide.
5. Repeat.

This clever resurrection loop uses Sidisi, Regent of the Mire as your engine, tapping the Regent to sacrifice Giant-Sized Flying Ant—whose mana value of 1 neatly steps up to fetch the mana value 2 Karmic Guide from your graveyard. When Karmic Guide enters the battlefield, its trigger brings the Ant right back, which in turn triggers to untap Sidisi so you can do it all over again. Meanwhile, Carrion Feeder acts as the designated executioner, giving you a safe way to bin Karmic Guide whenever you need to reset the loop and convert all this cyclical recycling into infinitely large +1/+1 counters.
