Haru, Hidden Talent + Dryad Arbor + Overgrown Estate + Rukarumel, Biologist

Haru, Hidden Talent

Dryad Arbor

Overgrown Estate

Rukarumel, Biologist

How it works

1. Play Dryad Arbor.
2. When Dryad Arbor enters as an Ally due to Rukarumel, Haru triggers, earthbending Dryad Arbor.
3. Activate Dryad Arbor by tapping it, adding .
4. Activate Overgrown Estate by sacrificing Dryad Arbor.
5. When Dryad Abor dies, Haru triggers, returning Dryad Arbor from your graveyard to the battlefield.
6. When Dryad Arbor enters as an Ally due to Rukarumel, Haru triggers, earthbending Dryad Arbor.
7. Resolve the Overgrown Estate ability.
8. Repeat from step 3.

By setting Rukarumel, Biologist to choose "Ally," every nontoken creature and creature card you own becomes an Ally, instantly turning Dryad Arbor into a land-creature Ally the moment it hits the battlefield. This triggers Haru, Hidden Talent to earthbend Dryad Arbor into an animated land that, crucially, will return to the battlefield tapped whenever it dies or is exiled. You can tap the resurrected Dryad Arbor for green mana, then feed it to Overgrown Estate to sacrifice the land for 3 life. Because Haru's earthbend replacement effect ensures Dryad Arbor continuously loops right back onto the battlefield to re-trigger its Ally status, this self-sustaining cycle generates infinite green mana, lifegain, and sacrifice triggers.
