Veinwitch Coven + Carnival of Souls + Case of the Uneaten Feast

Veinwitch Coven

Carnival of Souls

Case of the Uneaten Feast

How it works

1. Cast the creature card from your hand for 0. The creature enters, then immediately dies as a state-based action due to having 0 toughness.
2. When the creature enters, Carnival of Souls and Case of the Uneaten Feast trigger.
3. Resolve the Carnival of Souls ability, adding and losing 1 life.
4. Resolve the Case of the Uneaten Feast ability, gaining at least 1 life.
5. When you gain life, Veinwitch Coven triggers, causing you to pay to return the creature card from your graveyard to your hand.
6. Repeat.
