Sheoldred, the Apocalypse + Vilis, Broker of Blood + Cavern Harpy

Sheoldred, the Apocalypse

Vilis, Broker of Blood

Cavern Harpy

How it works

1. Activate Cavern Harpy by paying 1 life.
2. Vilis triggers, causing you to draw a card.
3. Sheoldred's first ability triggers, causing you to gain 2 life.
4. Repeat as desired.
5. Resolve all Cavern Harpy abilities.

This vicious loop starts by using Cavern Harpy's self-bounce ability, which requires paying 1 life just to return it to your hand. That life loss directly awakens Vilis, Broker of Blood, whose passive ability turns every point of lost life into a fresh card drawn. Enter Sheoldred, the Apocalypse: whenever those cards are drawn, her static life-gain triggers more than heal the wound, netting you positive life while flooding your hand with resources. You can simply replay the Harpy and repeat the process as many times as you desire, converting your life total into an endless fountain of cards and near-infinite life.
