Karn, Silver Golem + Salvaging Station + Treasure Vault

Karn, Silver Golem

Salvaging Station

Treasure Vault

How it works

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

This loop turns the land-cycling engine of Treasure Vault into a self-destructive engine by leveraging Karn, Silver Golem's active ability, which temporarily animates the land as an artifact creature with zero toughness. The moment Treasure Vault enters the graveyard from the battlefield, Salvaging Station's second ability triggers to untap itself, while its tap ability simultaneously lets you recur the land right back to the battlefield. Because Salvaging Station only requires a creature to die to untap itself—and Karn's animation naturally achieves this by instantly sending the zero-toughness Treasure Vault to the graveyard—you can repeat this continuous cycle to generate an infinite number of artifact entry, leave-the-battlefield, and death triggers.
