Saheeli's Artistry + Archaeomancer + Great Whale

Saheeli's Artistry

Archaeomancer

Great Whale

How it works

1. Activate up to seven lands by tapping them, adding at least 4.
2. Cast Saheeli's Artistry by paying 4, creating a token copy of Great Whale that is an artifact.
3. When the Great Whale token enters, it triggers, untapping up to seven lands.
4. Cast Archaeomancer by paying its mana cost.
5. When Archaeomancer enters, it triggers, returning Saheeli's Artistry from your graveyard to your hand.
6. Activate up to seven lands by tapping them, adding at least 4.
7. Cast Saheeli's Artistry by paying 4, creating a token copy of Archaeomancer and the Great Whale token.
8. When the Archaeomancer and Great Whale tokens enter, they trigger.
9. Resolve the Archaeomancer token's trigger, returning Saheeli's Artistry from your graveyard to your hand.
10. Resolve the Great Whale token's trigger, untapping up to seven lands.
11. Repeat from step 6.

This elegant loop achieves infinite recursion by cycling Saheeli's Artistry, Archaeomancer, and Great Whale through a self-sustaining mana engine. By using Saheeli's Artistry to copy Great Whale, you immediately untap your lands to net positive mana, while simultaneously copying Archaeomancer to recur the very same sorcery back to your hand. As you repeat this process, the growing army of token copies compounds your resources exponentially, generating infinite mana, infinite enters-the-battlefield triggers, and a boundless swarm of artifact creatures.
