Sword of the Paruns + Power Artifact + Orochi Merge-Keeper

Sword of the Paruns

Power Artifact

Orochi Merge-Keeper

How it works

1. Activate Orochi Merge-Keeper by tapping it, adding .
2. Activate Sword of the Paruns by paying 1, untapping Orochi Merge-Keeper.
3. Repeat.

This clever loop turns Orochi Merge-Keeper into a self-sustaining mana engine, fueled entirely by the cost-reduction magic of Power Artifact. Because Power Artifact makes the activated abilities of the enchanted artifact cost {2} less, the untap ability of Sword of the Paruns drops from three mana down to a mere single generic mana. Once you equip the Sword to Orochi Merge-Keeper, the snake monk becomes modified, boosting its tap ability to yield two green mana—more than enough to pay the discounted {1} untap cost and net endless green mana in the process.
