How it works
Activate Yahenni by sacrificing another creature.
Korvold's second ability triggers, putting a +1/+1 counter on it and causing you to draw a card.
The Locust God triggers, causing you to create a 1/1 Insect creature token with haste.
Resolve the Yahenni ability, giving it indestructible until end of turn.
Repeat.
This clever engine turns the sacrifice outlet Yahenni, Undying Partisan into a self-sustaining loop by feeding its ability with tokens generated on the fly. Whenever you sacrifice a creature to protect Yahenni, Korvold, Fae-Cursed King steps in with its triggered ability to pump itself up and force a card draw. That drawn card immediately rouses The Locust God, whose static and triggered abilities turn every single card drawn into a fresh 1/1 Insect token ready to be sacrificed right back to Yahenni.
