Sidisi, Regent of the Mire + Karmic Guide + Umbral Collar Zealot + Giant-Sized Flying Ant

Sidisi, Regent of the Mire

Karmic Guide

Umbral Collar Zealot

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 Umbral Collar Zealot by sacrificing Karmic Guide.
5. Repeat.

This clever loop leverages Sidisi, Regent of the Mire as a recurring reanimation engine, using its tap ability to sacrifice Giant-Sized Flying Ant and pull Karmic Guide straight from the graveyard. Karmic Guide immediately triggers upon entering to bring back the Giant-Sized Flying Ant, whose own entry trigger untaps Sidisi so the entire process can begin anew. Meanwhile, Umbral Collar Zealot provides the essential sacrifice outlet to bin Karmic Guide whenever the chain needs to reset, generating an endless stream of death triggers and surveil depth.
