Retreat to Emeria + Haru, Hidden Talent + Strip Mine + Stone-Seeder Hierophant

Retreat to Emeria

Haru, Hidden Talent

Strip Mine

Stone-Seeder Hierophant

How it works

1. Play Strip Mine.
2. When Strip Mine enters, Stone-Seeder Hierophant and Retreat to Emeria trigger.
3. Resolve the Stone-Seeder Hierophant trigger, untapping it.
4. Resolve the Retreat to Emeria trigger, creating a 1/1 Kor Ally creature token.
5. When the Kor Ally enters, Haru triggers, earthbending Strip Mine.
6. Activate Strip Mine's second ability by tapping and sacrificing it, targeting another land.
7. Haru triggers, returning Strip Mine from your graveyard to the battlefield tapped.
8. When Strip Mine enters, Retreat to Emeria and Stone-Seeder Hierophant trigger.
9. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping Strip Mine.
10. Repeat from step 3.

This clever loop turns the humble landfall mechanic into a relentless engine of land destruction by leveraging Haru, Hidden Talent to continually recycle Strip Mine. Whenever Strip Mine enters the battlefield, Stone-Seeder Hierophant and Retreat to Emeria trigger, with the latter churning out a 1/1 white Kor Ally token that prompts Haru to earthbend your Strip Mine into a creature. Because Haru ensures that sacrificed lands return to the battlefield, you can safely blow up Strip Mine for its land-destruction effect and have it immediately sneak back into play. With Stone-Seeder Hierophant on hand to untap Strip Mine through its activated ability, the entire sequence endlessly repeats, locking opponents out of the game entirely.
