Havengul Lich + Shambling Ghast + Blasting Station + Mirror Room // Fractured Realm

Havengul Lich

Shambling Ghast

Blasting Station

Mirror Room // Fractured Realm

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

This lethal loop is masterminded by Mirror Room // Fractured Realm's room ability, which doubles all of your permanent's triggered abilities to supercharge Shambling Ghast's death trigger into two Treasure tokens instead of one. With that mana generation self-sustaining, Havengul Lich steps in to repeatedly cast that same Shambling Ghast right back out of your graveyard for a single mana. Finally, Blasting Station acts as the ultimate executioner, using its tap-and-sacrifice ability to pick off opponents while its own untap trigger resets the loop every single time a creature enters the battlefield.
