Kairi, the Swirling Sky

High Tide

Turnabout

Fated Infatuation

How it works

1. Cast High Tide by paying .
2. Cast Fated Infatuation by paying its mana cost, creating a token copy of Kairi.
3. Put the Kairi token into your graveyard due to the legend rule.
4. When the Kairi token dies, it triggers, causing you to mill six cards and return High Tide and Fated Infatuation from your graveyard to your hand.
5. Cast High Tide by paying .
6. Activate at least three Islands by tapping them, adding .
7. High Tide triggers twice for each Island tapped this way, adding that much .
8. Cast Turnabout by paying 2, untapping all lands you control.
9. Cast Fated Infatuation by paying its mana cost, creating a token copy of Kairi.
10. Put the Kairi token into your graveyard due to the legend rule.
11. When the Kairi token dies, it triggers, causing you to mill six cards and return Turnabout and Fated Infatuation from your graveyard to your hand.

This mesmerizing loop turns Kairi, the Swirling Sky into an engine of recursive recycling by exploiting the legend rule. Whenever you sacrifice the extra Kairi copy, its death trigger lets you fish your spent spells right back out of the graveyard to keep the chain going. High Tide turbocharges your mana production so you can easily pay for everything, while Turnabout continually untaps your lands to keep the blue mana flowing. Finally, Fated Infatuation serves as the catalyst that clones Kairi over and over again, sustaining the cycle indefinitely.
