Rings of Brighthearth + Seeker of Skybreak + Selvala, Heart of the Wilds

Rings of Brighthearth

Seeker of Skybreak

Selvala, Heart of the Wilds

How it works

1. Activate Selvala by paying and tapping it, adding at least and three mana of any color(s).
2. Activate Seeker of Skybreak by tapping it, targeting itself.
3. Rings of Brighthearth triggers, causing you to pay 2 to copy Seeker of Skybreak's ability, targeting Selvala.
4. Resolve both Seeker of Skybreak abilities, untapping it and Selvala.
5. Repeat.

This clever pairing transforms an innocent elf into an engine for infinite mana by exploiting the passive mana generation of Selvala, Heart of the Wilds. When you tap Selvala for mana, her ability scales dynamically with the greatest power among creatures you control, funding the entire loop with plenty to spare. You then activate Seeker of Skybreak to untap Selvala, while Rings of Brighthearth steps in with its triggered ability to let you copy that untap effect for a mere two mana. By using the copied trigger to untap Seeker of Skybreak itself and the original to untap Selvala, you can repeat this dance endlessly to flood your mana pool with infinite colored mana.
