Karn, Silver Golem + Salvaging Station + Great Furnace

Karn, Silver Golem

Salvaging Station

Great Furnace

How it works

1. Activate Great Furnace by tapping it, adding .
2. Activate Karn by paying 1, causing Great Furnace to become a creature until end of turn.
3. Great Furnace dies as a state-based action due to having 0 toughness, triggering Salvaging Station, untapping Salvaging Station.
4. Activate Salvaging Station by tapping it, returning Great Furnace from your graveyard to the battlefield.
5. Repeat.

This engine transforms a simple land into a self-sacrificing loop by leveraging Karn, Silver Golem's ability to turn Great Furnace into a creature with a mana value of zero, which immediately perishes as a state-based action. That death trigger effortlessly untaps Salvaging Station, allowing you to tap the Station to pull Great Furnace right back out of the graveyard and onto the battlefield. Because Great Furnace is both a land and an artifact returning to play repeatedly, you gain a ceaseless cascade of enters-the-battlefield, leaves-the-battlefield, and death triggers to fuel your victory.
