Spirit Summoner Build Critique

[Some Other Guy]

The party this is for is level 10. We are under leveled for the challenges we are facing and decided to make a martial focus summoner because reasons. I can't happily play any class with less than 6 levels of spells, so summoner seemed like the logical choice. I don't care too much for summon monster and I love eidolons, and I'm fairly certain that the spirit summoner archetype with the battle spirit is a premium option. I'm looking for anything that I might have missed or don't incorrectly/poorly. Eidolon is standard pouncing quadraped. Here is what I have:

in order for the eidolon to pick up improved spell sharing you need to talk to your GM.
per RAW it is not allowed since the eidolon doesn't qualify for it (it doesn't have the ability to have an AC, eidolon, etc)

against tough foes i would vote against elemental aomf.

You kinda need to pick magic attacks for your eidolon too, to avoid some forms of DR which will harm you greatly

flight is also quite good evolution, it allows you to pounce that much easier, as well as offering supreme mobility

I'm aware of the teamwork feat's stupidly written requirements and would honestly not play with any GM that doesn't see them as stupidly written and contradictory.

Greater magic fang makes the eidolon's attacks magic. Overland flight gives both of us flight all day long. Worst case, like a dispel, I can use evolution surge.

magic evolution would also make your eidolons attack aligned, i saw that you had gmf

I understand how it works. I just don't feel it's worthwhile when Evolution Surge is a paltry first level spell when it's needed.
