Saheeli's Artistry + Great Whale + Revolutionist

Saheeli's Artistry

Great Whale

Revolutionist

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 Revolutionist by paying its mana cost.
5. When Revolutionist 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 Revolutionist and the Great Whale token.
8. When the Revolutionist and Great Whale tokens enter, they trigger.
9. Resolve the Revolutionist 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 clever loop turns Saheeli's Artistry into an engine of exponential growth by doubling up on entering-the-battlefield triggers. By using the spell to copy Great Whale, you immediately refund your mana investment by untapping your lands, while simultaneously bringing back Saheeli's Artistry from your graveyard with Revolutionist. Once you have accumulated enough copies of the Whale to generate a surplus of mana, subsequent casts of Saheeli's Artistry can duplicate both creatures at once—allowing Revolutionist to continuously recycle the spell while the Great Whale tokens keep your lands perpetually refreshed.
