I do hope they added the 'expensive material components' clause to Wish, then
Especially with Twin Eidolon.
The first one was, as mentioned, my first attempt at building an eidolon.
All in all, though, Summoner isn't that uber as itself. It depends on their Eidolon-crafting skills, what they get.
Would need 4 EP, so would lose fire resistance, magic attack and flight, for an example. CMB would be +38 with greater grapple and Grab.
Fair enough, it's an advanced class - requiring advanced gameplay skills.
Anyway, here's a look at 1-point evolutions only, with a quadruped for a change:

Well, that was pointless, if educational.
maximize number of attacks (as above), maximize STR, get Power Attack and it's a decent damage dealer, albeit it might be a bit of a glass cannon. That being said, Iron Body SLA 3/day costs 9 points, whilst abilities it grants cost quite a bit more.
