Battle of 2 under rated and under used females

The Eternal Sersi is one of the most powerful females in the Marvel Universe. She can pretty much do it all. But she rarely shows up in comics and they don't use her at her full potential. Photon has more appearances in Comic Battles than in actual comics. But which one is more powerful?

No BFR. Start 1000ft away. Win by K.O or incapacitated

Round 1: Sersi cant use telepathy. Photon has to stay solid and visible.

Round 2: No morals. No restrictions

Who wins each round and why?

Sersi can not die.

@e3zombie: can she be ko'ed or overloaded?

@pooty: She also has super durability so photon would have to do something pretty crazy to knock her out.

Sersi

Sersi would just transmute Photon into a tree

Sersi.
