Satya, Aetherflux Genius + Éomer, Marshal of Rohan + Exalted Sunborn

Satya, Aetherflux Genius

Éomer, Marshal of Rohan

Exalted Sunborn

How it works

1. Declare Satya as an attacker, triggering its ability, causing you to create two token copies of Éomer and causing you to get EE.
2. Put both Éomer tokens into your graveyard due to the legend rule.
3. Both Éomer tokens trigger, causing you to untap all creatures you control and to get two additional combat phases after this one.
4. Repeat each combat phase.

This loop relies on the explosive synergy between Satya, Aetherflux Genius, Éomer, Marshal of Rohan, and Exalted Sunborn to spiral completely out of control. When Satya swings, his attack trigger normally makes a single token copy, but Exalted Sunborn doubles that creation into two attacking tokens of Éomer, Marshal of Rohan instead. Because both Éomer tokens enter the battlefield as legendary copies of the same creature, the legend rule immediately sends them both to the graveyard, triggering their death abilities at the same time. This awards you an extra combat phase and untaps all your creatures—including Satya, Aetherflux Genius—allowing you to repeat the entire process indefinitely for infinite combat phases, energy, and death triggers.
