How it works

1. Activate Havengul Lich by paying 1, allowing you to cast Shambling Ghast card from your graveyard this turn.
2. Cast Shambling Ghast from your graveyard by paying .
3. When Shambling Ghast enters, Necroduality triggers, creating a token copy of Shambling Ghast.
4. Activate Carrion Feeder twice by sacrificing both Shambling Ghasts.
5. When the Shambling Ghasts die, they triggers, creating two Treasure tokens.
6. Resolve the Carrion Feeder ability.
7. Activate the Treasures by tapping and sacrificing them, adding 1.
8. Repeat.

This elegant engine turns a simple loop of the dead into endless power, fueled by Havengul Lich's ability to repeatedly pull Shambling Ghast from the graveyard for a single mana. As each Shambling Ghast enters the battlefield, Necroduality doubles your investment by immediately spawning an identical token copy of the Zombie. You then feed both the original and its token to Carrion Feeder, pumping it with infinite +1/+1 counters while sending the pair back to the graveyard. Finally, the death triggers from the dying Shambling Ghasts create Treasure tokens that you can crack for mana to pay for the Lich's activation, keeping the cycle spinning forever.
