Do a blaster with no metamagic feats.
ok I'm kidding
How much is this character allowed to be broken?
Edit- About the familiar used as a scout: you already have a Druid, and the Rogue is probably decent at scouting too. If you go for this, however, the best possible PHB familiar is the raven, as it flies and speak one language. It's a shame that you cannot use Complete Scoundrel, as th skill trick "listen to this" would be useful.
+1 on the God/utility. It can rarely be banned as broken but it actually is the edge that makes you win. Also the Druid have some lacks in some aspects of utility casting and buffing/debuffing.
It can be a little boring to play, thought, as it makes other characters shine instead of shining himself.
