Need Help picking classes

[Nosta]

so My 3.5 group had a new Idea
Rolling for races. I rolled changeling
and have never played one and I was wondering
what two classes would be good to build a strong Character for combat

We will start at level 15 and end at 20
My stats are !7 !7 16 16 15 13

Wizard. The 1st and 5th level substitution levels for Changeling Wizards are fantastic. And since you're starting at 15th level, you'll have 8th level spells right out of the gate, so you'll be extremely overpowered both in and out of combat.
