Havengul Lich + Shambling Ghast + Woe Strider + Teysa Karlov

Havengul Lich

Shambling Ghast

Woe Strider

Teysa Karlov

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

This clever loop uses Havengul Lich's ability to repeatedly pull Shambling Ghast from your graveyard, paying the Lich's activation cost and the Ghast's casting cost with the mana generated along the way. Woe Strider acts as the sacrifice outlet that sends the Ghast straight back to the graveyard while letting you filter your draws with its scry ability. The true engine that makes the math work is Teysa Karlov, whose static doubler turns the Shambling Ghast's single death trigger into two, producing a pair of Treasure tokens every cycle that outpace the costs and yield an infinite surplus of mana, sacrifices, and scrys.
