Brainstorming new character for mid-high OP game

[Vash9177]

I'm currently in a more high powered game as a wizard/shadowcraft mage however it's turning out to be more over the top then I thought it would be and after talking to my DM we both agreed that it would be better to look for a different character to run.

The rest of the party is as follows
An ubercharger that does about 250 per attack
A DMM persist cleric/walker in the waste
A soulbow with 4 arms and multi weapon fighting
And a DMPC that is a Factotum/Chameleon

We are currently at level 11.

So given all that I'm looking for a new character that can contribute to combat but not completely rule it and every other situation by itself. The story involves protecting the DMPC from organizations that what her dead so I thought an Adjuration focused wizard might be good or I've been playing with the idea of running a psionic character since I love the sub system but I'm not sure how to make a character with it that would fit this party. I'm also open to other suggestions if anyone has any.

For reference the rules of the campaign are
-Feat at every odd level
-All books allowed except for Faerun specific books
-Race + template can be up to LA +3 for free
-No more than 4 base and or PRCs may be used in the 20 level build
-No flaws
-Dragon magazine content may be approved on a case by case basis

So given all that what does the playground think I should do?

Sounds like you want some kind of caster to fill that role. Straight Psion would work well in the party, since they fill a similiar role as sorcerers.

For starters, Phrenic is a good choice for a template. That or Half Fey, but you wanted to be more psionic.

Master Abjurer is a strong choice if you're interested in protecting the party. The class makes you a natural anti-caster. Maybe try grabbing some Full BAB levels to enter Abjurant Champion.

My personal favorite arcane caster type is Swiftblade. Wizard6/Swiftblade5 at your level. Spelldancer fits in really well, but you said no Faerun.

I would probably go Wizard into Malconvoker. Conjuring variant wizard gets you standard action summons, you get 2 of each summoned creature and can afford a ring of mighty summons.

Phrenic is a really cool template and for psion which disciple do you recommend? Shapers seem cool but I'm not sure if Astral Constructs could keep up with the party.

For the Abjurer idea I had thought about using master specialist and Initiate of the Sevenfold Veil for a high dispeller and shield for the PC we need to protect. Actually on that idea I vaguely remember an AFC that was in a dragon magazine that let an Abjurer use a shield and it provided a few other benefits.

Swiftblade is a really cool class but in another game I'm playing a gish druid and wanted to try more of a supporting role for this game.

Doing a summoner might be fun but I'll admit I only have first hand experience with it from a Druid build. What's a good way to run a Malconvoker do you focus more on utility summons or combat summons?

You can do everything (http://community.wizards.com/forum/previous-editions-character-optimization/threads/1131936)!

Basically you get enhanced HD caps on the planar binding line and the ability to summon two top level evil monsters with each summon monster spell. Your highest level summon at level 11 (5 Wizard, 6 Malconvoker) is going to be summon monster V. You have augment summon on them, and should probably use a ring of mighty summons (maximizes hit points.) Summon Monster V and IV are going to be for combat, especially using pairs of Fiendish Giant Crocodiles with 101 HP each (200 HP a summon) and lots of lockdown.

For Summon Monster IV I would not use the ring and summon a pair of large monstrous spiders to throw webs on enemies, which entangles them.

For utility there is the Summon Elemental Reserve Feat, which allows you to summon a single elemental an infinite number of times if you have a summon monster slot open. Have it open every door and walk in front of the party to deal with traps.
