Nim Deathmantle + The Master of Lake-town + Blasting Station + Mind Over Matter

Nim Deathmantle

The Master of Lake-town

Blasting Station

Mind Over Matter

How it works

1. Activate Blasting Station by tapping it and sacrificing The Master of Lake-town.
2. When The Master of Lake-town dies, it and Nim Deathmantle trigger.
3. Resolve the Master of Lake-town trigger, drawing a card for each graveyard that has seven or more cards in it.
4. Holding priority, activate a mana-producing permanent by tapping it, adding at least 1.
5. Activate Mind Over Matter by discarding a card, untapping the mana-producing permanent
6. Repeat steps 4 and 5 until you have 4 or more available.
7. Resolve the Nim Deathmantle trigger, causing you to pay 4 to return The Master of Lake-town from your graveyard to the battlefield and attaching Nim Deathmantle to it.
8. When The Master of Lake-town enters, Blasting Station triggers, untapping Blasting Station.
9. Resolve the Blasting Station ability from step 1
10. Repeat.

This vicious loop uses Blasting Station to sacrifice The Master of Lake-town, which immediately triggers both its own death ability and Nim Deathmantle's resurrection engine. As The Master of Lake-town hits the graveyard, it also feeds its own death-draw ability and sets up the life loss that its mill trigger cares about. By utilizing Mind Over Matter's discard ability, you can cycle through your hand to generate the exact mana needed to pay Nim Deathmantle's {4} revival cost. Every time The Master of Lake-town is brought back to the battlefield, Blasting Station untaps itself thanks to its own creature-entry trigger, allowing you to repeat the whole process endlessly.
