Living Death + Archaeomancer + Great Whale + Viscera Seer

Living Death

Archaeomancer

Great Whale

Viscera Seer

How it works

1. Activate up to seven lands you control by tapping them, adding at least 3.
2. Activate Viscera Seer twice by sacrificing Archaeomancer and Great Whale, causing you to scry 1 twice.
3. Cast Living Death by paying 3, causing each player to exile all creature cards from their graveyard, sacrifice all creatures they control, then return all cards exiled this way to the battlefield.
4. Archaeomancer and Great Whale enter the battlefield, triggering their abilities.
5. Resolve the Archaeomancer trigger, returning Living Death from your graveyard to your hand.
6. Resolve the Great Whale trigger, untapping up to seven lands you control.
7. Repeat.
8. If the seven lands can tap to produce at least 4, this combo nets infinite mana.

This loop relies on the cyclical power of Living Death to continuously swap your graveyard and battlefield, creating an engine that feeds itself indefinitely. By using Viscera Seer to sacrifice both Archaeomancer and Great Whale, you clear the way for Living Death to resurrect them both simultaneously. When they return, Great Whale untaps your lands to pay for the spell, while Archaeomancer plucks Living Death right back out of your graveyard to hand, leaving you free to repeat the entire process while generating infinite mana, scry triggers, and sacrifices.
