Havengul Lich + Rooftop Storm + Warren Soultrader + Leyline of Vitality

Havengul Lich

Rooftop Storm

Warren Soultrader

Leyline of Vitality

How it works

1. Activate Havengul Lich by paying 1, allowing you to cast a Zombie from your graveyard this turn.
2. Cast the Zombie from your graveyard by paying 0 due to Rooftop Storm.
3. When the Zombie enters the battlefield, Leyline of Vitality triggers, causing you to gain 1 life.
4. Activate Warren Soultrader by paying 1 life and sacrificing the Zombie, creating a Treasure token.
5. Activate the Treasure by tapping and sacrificing it, adding 1.
6. Repeat.

This loop transforms your graveyard into an engine of endless life and treasures by combining cost-reduction with recycling. Thanks to Rooftop Storm, you can cast creature cards from your graveyard for free once Havengul Lich gives you permission to do so. Warren Soultrader then converts those free recasted creatures into Treasure tokens and pays for the life you lost while doing so, while Leyline of Vitality cushions the cost by turning every single creature entry into a net-positive life buffer.
