This is from another thread, but seems like a relevant answer here:
An Scion of Humanity Aasimar Seeker Archetype Lunar Oracle is perfect for this situation (though that is largely because all of that except the Archetype is largely perfect for *any* and *all* situations).
Make sure you grab a grab a tiger with your first revelation and you'll have a great tank. You can even make it more durable quickly by using the Aasimar favored class bonus to fast advance it and you can pick up the Celestial Servant feat to have a Celestial Tiger at 3rd.
Seeker Archetype lets you cover the trapfinding role of the scout. You have 4+INT skill points and are a CHA focused class so you make an excellent face for the group. If desired you can take Racial Heritage (Half-Elf) at 5th level so you can get paragon surge as a spell at level 6. After that you just need Skill Focus (any knowledge) and Eldritch Heritage and your ready to know all the spells at level 11.
Don't forget to grab the Noble Scion Feat (War) at level 1 so you get CHA to initiative and Prophetic Armor at 3rd so you get CHA to AC/Reflex.
