Just out of Core: Dimension Door(Dimension Hop IIRC is a lower level version from the Duskblade List in PHB II), Haste(good buff, even better if you already have summons out), Vampiric Touch(Scary Bear + Temp HP = Scary Bear that doesn't need spells to heal himself) and maybe Shadow Conjuration(personal favorite of mine, for quasireal Phantom Steeds & Unseen Servants. Glitterdust, Web, Mage Armor could backfire if disbelieved, but are all useful in their own right).
