Battlemage's Bracers + Deathbloom Ritualist + Tidewater Minion

Battlemage's Bracers

Deathbloom Ritualist

Tidewater Minion

How it works

1. Activate Deathbloom Ritualist by tapping it, adding at least two mana of any color
2. Activate Tidewater Minion by tapping it, targeting Deathbloom Ritualist.
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 Deathbloom Ritualist.
5. Repeat.

This clever loop relies on Tidewater Minion to repeatedly untap your key permanents, but the real magic happens when Battlemage's Bracers steps in to multiply that untap trigger for a modest mana fee. Because Deathbloom Ritualist generates enough mana from the graveyard to easily cover both the activation and the copy cost, you generate a net surplus of colored mana on every single iteration. As long as Deathbloom Ritualist feeds the chain with enough creature cards in your graveyard, the Bracers turn a simple untap loop into an infinite engine.
