How it works
Activate Bartolomé del Presidio by sacrificing Marionette Master.
When Marionette Master dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
When Marionette Master enters, its fabricate ability triggers, putting a +1/+1 counter on it.
Resolve the Bartolomé del Presidio ability.
Repeat.
This ingenious loop centers around Marionette Master, which uses its fabricate ability to generate three +1/+1 counters upon entering the battlefield. With the help of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight granting its backside's persist ability to your other nontoken creatures, Marionette Master returns from the graveyard with a single -1/-1 counter whenever it dies. State-based actions immediately cancel out that -1/+1 counter and one of the creature's +1/+1 counters, leaving Marionette Master free to be repeatedly sacrificed to Bartolomé del Presidio. As Marionette Master continuously enters and dies as an artifact creature, its own triggered ability triggers over and over again to drain infinite life from your opponents.
