Beledros Witherbloom + Ancestor's Prophet + Emiel the Blessed + Living Plane + Arcane Adaptation

Beledros Witherbloom

Ancestor's Prophet

Emiel the Blessed

Living Plane

Arcane Adaptation

How it works

1. Activate Ancestor's Prophet by tapping five lands you control, causing you to gain 10 life.
2. Activate any number of other lands you control by tapping them, adding at least 3.
3. Activate Beledros by paying 10 life, untapping all lands you control.
4. Activate Emiel the Blessed by paying 3, blinking Beledros.
5. Repeat.
6. If the additional lands can tap to produce at least 4, this combo nets infinite mana.

This intricate engine transforms your entire land base into a massive, unified workforce through Living Plane, which turns every land into a 1/1 creature. Arcane Adaptation then binds the board together by declaring every creature you control—including all those land-creatures—to be Clerics, which allows Ancestor's Prophet to tap five of them to generate a massive 10 life cushion. That life buffer fuels Beledros Witherbloom's ability to pay 10 life to untap all your lands, which Emiel the Blessed then blinks away for three mana to reset the dragon's once-per-turn restriction and let you loop the whole process indefinitely.
