This clever loop feeds on itself by turning sacrifices into fresh cards and fresh cards into new sacrifices. When you use Bartolomé del Presidio to snack on the Insect token provided by The Locust God, Korvold, Fae-Cursed King eagerly steps in to reward that sacrifice with both a +1/+1 counter and a crucial card draw. That newly drawn card immediately triggers The Locust God once again to hatch a brand-new token, letting you continuously cycle sacrifices to endlessly grow your board and your threats.
