Havengul Lich + Rooftop Storm + Warren Soultrader + Ajani's Welcome

Havengul Lich

Rooftop Storm

Warren Soultrader

Ajani's Welcome

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, Ajani's Welcome 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 elegant loop turns your graveyard into an engine of endless life and treasures by bridging casting costs with sacrifice economics. With Rooftop Storm making your Zombie creature spells completely free to cast, Havengul Lich steps in to let you repeatedly pull that same Zombie right back out of your graveyard for just one mana. Each time the creature returns, Ajani's Welcome cushions your life total by granting you 1 life upon entry, offsetting the cost to feed Warren Soultrader. You then sacrifice that Zombie to Warren Soultrader to generate a Treasure token, which you immediately crack for mana to fund the Lich's activation all over again.
