Cast Fake Your Own Death by paying 1, targeting any creature.
Holding priority, cast Dualcaster Mage by paying 1.
When Dualcaster Mage enters the battlefield, it triggers, copying Fake Your Own Death, targeting Dualcaster Mage.
Resolve the copy of Fake Your Own Death.
Holding priority, activate Viscera Seer by sacrificing Dualcaster Mage.
When Dualcaster Mage dies, it triggers, returning itself from your graveyard to the battlefield and creating a Treasure token.
Repeat from step 3.
Resolve all Viscera Seer abilities, causing you to scry 1 that many times.
This clever loop hinges on the synergy between Dualcaster Mage, Viscera Seer, and Fake Your Own Death to continuously recycle the Mage for infinite value. By casting Fake Your Own Death and responding with Dualcaster Mage to copy it onto itself, you set up a perpetual motion machine where sacrificing the Mage to Viscera Seer triggers its own immediate return to the battlefield—simultaneously generating a Treasure token for mana and endlessly fueling the Viscera Seer to scry your entire deck.
