Havengul Lich + Shambling Ghast + Bloodflow Connoisseur + Delney, Streetwise Lookout

Havengul Lich

Shambling Ghast

Bloodflow Connoisseur

Delney, Streetwise Lookout

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. Activate Bloodflow Connoisseur by sacrificing Shambling Ghast.
4. When Shambling Ghast dies, it triggers twice, creating two Treasure tokens.
5. Resolve the Bloodflow Connoisseur ability.
6. Activate the Treasures by tapping and sacrificing them, adding 1
7. Repeat.

This loop turns a simple graveyard recursion trick into a self-sustaining engine, powered entirely by Delney, Streetwise Lookout doubling the death trigger of Shambling Ghast whenever it hits the graveyard. Havengul Lich acts as the conductor, letting you repeatedly cast the Ghast from your graveyard by filtering the mana generated by the Ghast's own Treasure tokens. Meanwhile, Bloodflow Connoisseur serves as the sacrifice outlet that feeds the loop while growing to infinite size, turning the mana and death triggers into an overwhelming advantage.
