Beifong's Bounty Hunters + Bartolomé del Presidio + Eusocial Engineering

Beifong's Bounty Hunters

Bartolomé del Presidio

Eusocial Engineering

How it works

1. Activate Bartolomé del Presidio by sacrificing another nonland creature you control.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land.
3. Resolve the Bartolomé del Presidio ability.
4. Activate Bartolomé del Presidio by sacrificing the land.
5. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield tapped.
6. When the land enters, Eusocial Engineering triggers, creating a creature token.
7. Resolve the Bartolomé del Presidio ability.
8. Repeat.

This clever engine turns the simple act of sacrifice into an expanding loop by letting your lands pull double duty as recursive fodder. You feed a creature to Bartolomé del Presidio, which triggers Beifong's Bounty Hunters to earthbend a land into a 0/0 creature pumped full of +1/+1 counters. Because that land-creature is now fair game, you sacrifice it right back to Bartolomé del Presidio, and its death triggers Beifong's Bounty Hunters' safety net to return it safely to the battlefield tapped. That new arrival triggers Eusocial Engineering to produce a fresh 2/2 Robot artifact creature token, which immediately refills your sacrificial vault so you can repeat the process indefinitely.
