Karn, Silver Golem + Salvaging Station + Darksteel Citadel

Karn, Silver Golem

Salvaging Station

Darksteel Citadel

How it works

1. Activate Darksteel Citadel by tapping it, adding C.
2. Activate Karn by paying 1, causing Darksteel Citadel to become a creature until end of turn.
3. Darksteel Citadel 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 Darksteel Citadel from your graveyard to the battlefield.
5. Repeat.

This ingenious loop relies on turning your lands into creatures so they can feed the graveyard and fire off triggers. By using Karn, Silver Golem's ability to animate a Darksteel Citadel into an artifact creature with a mana value of 0, the land immediately crashes into the graveyard as a state-based action with zero toughness. That death triggers Salvaging Station, which gladly taps to pluck the indestructible Darksteel Citadel right back out of your graveyard and onto the battlefield. Because the Citadel survives the trip thanks to its indestructible nature, you can repeat this dance endlessly to farm infinite artifact entry, exit, and death triggers.
