How it works

1. Cast Etali by paying 5
2. When Etali enters, it triggers.
3. Holding priority, activate Yahenni by sacrificing Etali.
4. When Etali dies, Yedora triggers, returning Etali from your graveyard to the battlefield face-down as a Forest land.
5. Resolve the Yahenni ability.
6. Holding priority, activate Etali by tapping it, adding .
7. Resolve the Etali trigger from step 2, exiling cards from the top of each library until each player has exiled a nonland card, and causing you to cast any number of those cards without paying its mana cost.
8. For each card cast, Toph's second ability triggers once.
9. Resolve the first Toph trigger, earthbending Etali.
10. Resolve any remaining triggers, earthbending any other lands you desire. If you do not want to earthbend other lands, target Etali with all remaining triggers.
11. Activate Yahenni by sacrificing Etali.
12. When Etali dies, Toph and Yedora trigger.
13. Resolve the Yedora trigger, choosing not to return Etali.
14. Resolve the Toph trigger, returning Etali from your graveyard to the battlefield tapped.
15. Repeat from step 2.
16. Resolve all Yahenni abilities from step 11.

This ingenious loop lets you recast Etali, Primal Conqueror over and over by treating the colossal dinosaur as both a sacrificial offering and a land, turning every iteration into an avalanche of value. When Etali enters the battlefield, its trigger lets you cast free spells from libraries, which in turn causes Toph, Hardheaded Teacher to earthbend your lands and fuel your mana reserves. Meanwhile, Yedora, Grave Gardener and Yahenni, Undying Partisan work in tandem to continuously cycle Etali through your graveyard and back to the battlefield—with Toph's graveyard recovery ready to loop the legendary dinosaur right out of the dirt.
