Delina, Wild Mage + Lightning Runner + Harmonic Prodigy + Aethertorch Renegade

Delina, Wild Mage

Lightning Runner

Harmonic Prodigy

Aethertorch Renegade

How it works

1. Declare Delina and Lightning Runner as attackers, triggering Delina twice and Lightning Runner once.
2. Resolve a Delina trigger, creating at least one token copy of Aethertorch Renegade that enters the battlefield tapped and attacking.
3. When the Aethertorch Renegade token(s) enter the battlefield, they trigger, causing you to get at least EEEE.
4. Repeat from step 2 for the remaining Delina trigger.
5. Resolve the Lightning Runner trigger, causing you to get EE and pay eight E to untap all creatures you control and to get an additional combat phase after this one.
6. At the end of your combat phase, each creature token created by Delina triggers, exiling themselves.
7. Repeat each combat phase.
8. Once you have infinite E, you may target any other creature(s) you control.

This explosive loop relies on Harmonic Prodigy amplifying the Wizard triggers of both Delina, Wild Mage and Aethertorch Renegade to rapidly snowball your resources. When Delina attacks alongside Lightning Runner, Harmonic Prodigy doubles Delina's attack trigger so you can copy Aethertorch Renegade multiple times, and each resulting token enters with a fresh burst of energy thanks to Aethertorch Renegade's own entry ability. Meanwhile, Lightning Runner generates energy on attacks and cashes it in to fund extra combat phases, letting Delina, Wild Mage swing over and over again to generate infinite copies, tokens, and energy.
