How it works

1. Activate Viscera Seer by sacrificing Nether Traitor.
2. Activate Viscera Seer by sacrificing another creature.
3. When the creature dies, Nether Traitor triggers, causing you to pay to return Nether Traitor from your graveyard to the battlefield.
4. Kheru Goldkeeper and Insidious Roots triggers, creating a Treasure token, a 1/1 Plant creature token and putting a +1/+1 counter on each Plant you control.
5. Resolve the Viscera Seer ability.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Repeat.
