Veinwitch Coven + Carnival of Souls + Healer of the Pride

Veinwitch Coven

Carnival of Souls

Healer of the Pride

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 Healer of the Pride trigger.
3. Resolve the Carnival of Souls ability, adding and losing 1 life.
4. Resolve the Healer of the Pride ability, gaining 2 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.
