This is an interesting strategy which I think would only be workable if the DM is bad at Sense Motive.
And bad at the rules.
Some of my favorite 3E spells and spell combinations include:
Extend Mage Armor
Extend Bull Strength plus Improved Invisibility on a Rogue who uses a two handed weapon (I prefer the Improved Invisibility to come from a Wand that I created with my Craft Wands feat, then I can give it to multiple PCs and multiple combats)
Round one: Haste/True Strike
Round two: Spectral Hand/Extend Vampiric Touch
(I know this is costly for something which is not deadly, but at high level, it's fun due to 95% hit chance and no save, and of course, nothing prevents you from casting more True Strike/Vampiric Touch combos in latter rounds, especially against foes whom combatant allies have severely damaged or enemy spell casters who have fewer hit points)
This last combo with Ghoul Touch (instead of Extend Vampiric Touch) against enemy Bards, Rogues, Sorcerers or Wizards. It is even more likely to succeed if you have Spell Focus Necromancy.
Round one: Haste/whatever
Round two: Evard's Black Tentacles/Solid Fog
Round one: Grease
Round two: Evard's Black Tentacles
(You could really bend the rules with Sculpt (from Tome and Blood) Grease, you should use Widen Spell, but Sculpt gives the larger area to you cheaper)
Round one: Web
Round two: Evard's Black Tentacles
(cast 15 feet into the Web since you can still see to cast even with 75% cover)
Round one: Haste/True Strike
Round two: Throw Tanglefoot bag/Evard's Black Tentacles
Round one: Wall of Force, Hemisphere, 6 inches off the ground
Round two: crouch down and cast Evard's Black Tentacles under edge of wall
(requires outdoors or 15 foot tall / 30 foot long/wide room)
Dispel Magic, one of the most underrated spells around.
Mirror Image is one of the best defensive spells against melee and missile users. It often prevents you from getting hit, even if an opponent is readying for you to cast.
Round one: Improved Invisibility
Round two: Silent Major (or Minor) Image
(outdoors, your opponents think you cast Dimension Door and then run off several hundred feet away to attack you. Once they get near the image, you then stop concentrating on it and start casting other spells. Since you are casting Major Image, you can have it react to their attacks and pretend to cast spells. In the meantime, you could slowly move away from your original position)
Round one: Improved Invisibility
Round two: Fly
(then you no longer even need to cast spells, just fire your light crossbow and move each round, but you need to be outdoors or in a room 15+ feet tall)
Hold Person against any non-spell caster. Combine with Spell Focus Enchantment and Coup de Grace.
Darkness in a smaller room 2 to 3 feet off the ground. With a lit torch on the ground, have your bowmen then crouch down and pepper everyone and constantly move away from anyone approaching.
Granted, many of the spell combinations can only be done once per day and Evard's does not work against Halflings or Gnomes.
