Battlemage's Bracers + Priest of Titania + Aphetto Alchemist

Battlemage's Bracers

Priest of Titania

Aphetto Alchemist

How it works

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

By equipping Aphetto Alchemist with Battlemage's Bracers, you turn its routine untap ability into a recursive engine; whenever you activate it, the Bracers let you pay {1} to copy the effect so you can untap both the Alchemist and Priest of Titania simultaneously. With Priest of Titania tapping for enough green mana to comfortably fund this copying tax, the excess green mana compounds into an infinite surplus. This looping mechanism ultimately lets you generate infinite mana and infinite untaps of your creatures.
