Delina, Wild Mage + Lightning Runner + Harmonic Prodigy + Bristling Hydra

Delina, Wild Mage

Lightning Runner

Harmonic Prodigy

Bristling Hydra

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 Bristling Hydra that enters the battlefield tapped and attacking.
3. When the Bristling Hydra token(s) enter the battlefield, they trigger, causing you to get at least EEE.
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 combo turns a chaotic dice roll into an unstoppable infinite engine by amplifying every trigger in sight. When Delina, Wild Mage attacks alongside Lightning Runner, Harmonic Prodigy doubles Delina’s attack triggers, allowing you to repeatedly target Bristling Hydra and flood the board with attacking token copies. Each newly arriving Bristling Hydra feeds your energy reserves through its entrance ability, quickly generating more than enough surplus to pay for Lightning Runner's heavy energy cost and chain together infinite combat phases.
