Tiefling Wizard5/DivineOracle2/Loremaster4/IotSV7/Archmage2
Assuming you have an 18 Int (20 after racials, 22 after level 8 bumps, 24 after +2 Int Headband). This gives you a +7 modifier which qualifies you for the bonus feat at level 8.
1st Quicken Spell
1st B Scribe Scroll
3rd Metamagic School Focus (CMage)
5th Sculpt Spell (CArc)
6th Spell Focus (Abjuration)
8th Greater Spell Focus (Abjuration)
9th Skill Focus: Spellcraft
12th Arcane Mastery (CArc)
15th Minor Shapeshift (CMage)
18th Spell Focus (Conjouration)
You just have to visit the Frog God's Fane before level 5 (or spend the 3000g if you create the character above level 5 or so). That gives you the Skill Focus(Knowledge: Religion) feat you need for both Divine Oracle and Loremaster. Quicken Spell is a bit early, but its the best no-prereq metamagic feat. Sculpt Spell requires one other, which you won't have.
Minor Shapeshift is AMAZING for high level survivability. Just keep a 4th level or higher Polymorph subschool spell prepped and on any turn you don't cast a quickened spell, retrigger the temp HPs.
You have to spend a lot of feats on prereqs, which hurts, but IotSV is strong enough to warrent it. For your 2nd Loremaster secret, I'd get the +2 Fort saves, and for your 2 Archmage High Arcanas, I'd grab SLA: Time Stop and probably either SLA: Shapechange, or Master of Shaping if you can retrain Sculpt Spell.
