Blight Mound

How it works

1. Activate Blasting Station by tapping it and sacrificing Tenacious Dead.
2. When Tenacious Dead dies, it, Blight Mound, and Pitiless Plunderer trigger.
3. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
4. Resolve the Blight Mound trigger, creating a creature token.
5. When the token enters, Blasting Station triggers, untapping itself.
6. In response to the remaining trigger, activate Blasting Station by tapping it and sacrificing the creature token.
7. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
8. Resolve the Blasting Station ability from step 6.
9. Activate two Treasure tokens by tapping and sacrificing them, adding .
10. Resolve the Tenacious Dead trigger, paying 1 to return it to the battlefield from your graveyard.
11. When Tenacious Dead enters, Blasting Station triggers, untapping itself.
12. Resolve the Blasting Station ability from step 1.
13. Repeat.

This infinite damage loop relies on a clever loop of sacrifices and triggers centered around Blasting Station to continuously churn through your creatures. When you sacrifice Tenacious Dead to the Station, Pitiless Plunderer and Blight Mound both react to the death: the Plunderer generates a Treasure token to help fund the resurrection, while the Mound provides a Pest token as a substitute sacrifice. Sacrificing that Pest token to Blasting Station repeats the death cycle to generate a second Treasure, allowing you to easily pay the {1}{B} required by Tenacious Dead's own ability to return itself to the battlefield and reset the entire mechanism.
