Priest of Titania + Rings of Brighthearth + Aphetto Alchemist

Priest of Titania

Rings of Brighthearth

Aphetto Alchemist

How it works

1. Activate Priest of Titania by tapping it, adding at least .
2. Activate Aphetto Alchemist by tapping it, targeting itself.
3. Rings of Brighthearth triggers, causing you to pay 2 to copy Aphetto Alchemist's ability, targeting Priest of Titania.
4. Resolve both Aphetto Alchemist abilities, untapping it and Priest of Titania.
5. Repeat.

This ingenious loop relies on a clever synergy between Aphetto Alchemist and Rings of Brighthearth to repeatedly untap your entire board. When you activate the Alchemist to untap itself, Rings of Brighthearth triggers to copy the ability, allowing you to also untap Priest of Titania with the copy. Since Priest of Titania taps to generate an abundance of green mana thanks to the Elves on the battlefield, you easily have enough fuel to pay the {2} required to copy the Alchemist's ability over and over again.
