Havengul Lich + Phyrexian Altar + Crimson Kobolds

Havengul Lich

Phyrexian Altar

Crimson Kobolds

How it works

1. Activate Phyrexian Altar by sacrificing Crimson Kobolds, adding one mana of any color.
2. Activate Havengul Lich by paying 1, targeting Crimson Kobolds.
3. Cast Crimson Kobolds from graveyard by paying 0.
4. Repeat.

This clever loop relies on the zero-mana cost of Crimson Kobolds to create an endless engine of sacrifice and rebirth. By paying into Havengul Lich's activation cost, you target the Kobolds in your graveyard, allowing you to recast them for free. Once they hit the battlefield, you immediately feed them to Phyrexian Altar to generate mana of any color, which in turn helps fund the Lich's ability to pull them back from the graveyard all over again.
