Saheeli's Artistry + Eternal Witness + Great Whale

Saheeli's Artistry

Eternal Witness

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 Eternal Witness by paying its mana cost.
5. When Eternal Witness 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 Eternal Witness and the Great Whale token.
8. When the Eternal Witness and Great Whale tokens enter, they trigger.
9. Resolve the Eternal Witness 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 delightful loop transforms a single casting of Saheeli's Artistry into a self-sustaining engine of creation. By starting with Great Whale to refund your mana upon entry, you set the stage for Eternal Witness to continuously fish Saheeli's Artistry right back out of your graveyard. Once both targets are available, multiplying them together lets you generate infinite mana, endless recursion, and an army of copies that takes over the board in a single sweeping gesture.
