Havengul Lich + Rooftop Storm + Warren Soultrader + Susurian Voidborn

Havengul Lich

Rooftop Storm

Warren Soultrader

Susurian Voidborn

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. Activate Warren Soultrader by paying 1 life and sacrificing the Zombie.
4. When the Zombie dies, Susurian Voidborn triggers, causing you to gain 1 life and an opponent to lose 1 life.
5. Resolve the Warren Soultrader ability, creating a Treasure token.
6. Activate the Treasure by tapping and sacrificing it, adding 1.
7. Repeat.

This elegant loop turns your graveyard into a perpetual engine by combining Havengul Lich's ability to cast creatures from the graveyard with Rooftop Storm, which reduces those Zombie casting costs to a free {0}. Once the Zombie is on the field, Warren Soultrader steps in to turn it into a Treasure token through sacrifice, paying back the Lich's activation cost and netting you infinite resources. Meanwhile, Susurian Voidborn sits patiently on the board, converting every single iteration of this cycle into a draining life swing against your opponents while padding your own total.
