Battlemage's Bracers + Aphetto Alchemist + Bighorner Rancher

Battlemage's Bracers

Aphetto Alchemist

Bighorner Rancher

How it works

1. Activate Bighorner Rancher by tapping it, adding at least .
2. Activate Aphetto Alchemist by tapping it, targeting Bighorner Rancher.
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 Bighorner Rancher.
5. Repeat.

By outfitting Aphetto Alchemist with Battlemage's Bracers, you transform its standard untap ability into a dual-targeting engine whenever you pay the extra mana. This allows the Alchemist to simultaneously untap itself and Bighorner Rancher, whose own tap ability yields a surplus of green mana thanks to the scaling power on your board. As you loop this sequence, Battlemage's Bracers copies the untap repeatedly, letting Bighorner Rancher fund the entire operation while generating infinite green mana along the way.
