Sidisi, Regent of the Mire + Karmic Guide + Bartolomé del Presidio + Giant-Sized Flying Ant

Sidisi, Regent of the Mire

Karmic Guide

Bartolomé del Presidio

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 Bartolomé del Presidio by sacrificing Karmic Guide.
5. Repeat.

This clever recursive loop turns a modest graveyard into an engine of endless value, fueled by Sidisi, Regent of the Mire tapping to sacrifice Giant-Sized Flying Ant and pull Karmic Guide from the graveyard. As Karmic Guide enters, its triggered ability recycles Giant-Sized Flying Ant right back to the battlefield, which conveniently untaps Sidisi for the next iteration using its own entering-the-battlefield untap mode. Meanwhile, Bartolomé del Presidio acts as the essential sacrifice outlet to cleanly send Karmic Guide away when needed and permanently grow its own size with endless +1/+1 counters.
