Battlemage's Bracers + Tidewater Minion + Rainveil Rejuvenator

Battlemage's Bracers

Tidewater Minion

Rainveil Rejuvenator

How it works

1. Activate Rainveil Rejuvenator by tapping it, adding at least .
2. Activate Tidewater Minion by tapping it, targeting Rainveil Rejuvenator.
3. Battlemage's Bracers triggers, causing you to pay 1 to copy Tidewater Minion's ability, targeting Tidewater Minion.
4. Resolve both Tidewater Minion abilities, untapping it and Rainveil Rejuvenator.
5. Repeat.

This elegant looping engine turns Battlemage's Bracers and Tidewater Minion into a self-contained untap machine. Because Battlemage's Bracers copies the tap ability of Tidewater Minion for a modest fee of {1}, a single activation snowballs into the ability to untap both the Minion and any other creature you control. Fueling this engine is Rainveil Rejuvenator, which taps to generate green mana based on its power to easily cover the costs required to keep the copying chain going indefinitely.
