Feats for a Syntheist

[Yanisa]

Heya everyone,

Once again I have troubles deciding, so I turn to you again.

What feat would you recommend as a level 3 feat for a Syntheist Summoner?

Level 1 was Extra Evolution and I got 5 up to 13 figured out too, but 3 is a hard one. Too many feats have minor benefits and the good ones (power attack) I want have requirements I can't met.

Arcane strike isn't bad as it applies to all natural attacks for the cost of a swift per round.

Improved Initiative is always awesome; Arcane Strike as mentioned, which has the added bonus of scaling well with level and number of attacks; Combat Expertise if you want to take advantage of the Eidolon's large size.
