Rings of Brighthearth + Seeker of Skybreak + Incubation Druid

Rings of Brighthearth

Seeker of Skybreak

Incubation Druid

How it works

1. Activate Incubation Druid by tapping it, adding three mana of any color a land you control could produce.
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 Incubation Druid.
4. Resolve both Seeker of Skybreak abilities, untapping it and Incubation Druid.
5. Repeat.

This clever loop turns a modest mana dork into a powerhouse by leaning heavily on the activated abilities of Seeker of Skybreak and Incubation Druid. Once Incubation Druid is pumped up with a +1/+1 counter, it taps for a hefty three mana, easily fueling the repeating cycle while leaving plenty left over. Meanwhile, Rings of Brighthearth sits quietly on the battlefield waiting for an activated ability, letting you pay a little extra mana to copy the untap effect and chain together an infinite cascade of untaps and mana.
