I'm looking at building a first level gestalt crusader for a PvP arena game. The combats will be me against another player built with similar rules. Characters are built with gestalt rules, 36 point buy and most 3.5 books.
I have PHB II, most of the completes, Book of 9 Swords, Libris Mortis, Book of Vile Deeds, Eberron Campaign Setting, Spell Compendium and MM III, so I'd like to focus on those books.
For one side of the gestalt, I want to try a Crusader (Bo9S). For the other side, I'm looking at some sort of spell caster for buffing. Several of the Crusader's abilities key of off Charisma, so I'd like a Charisma based caster rather than Int based.
There's several useful looking spells on the Sorcerer spell list (Blades of Fire, Wraith Strike, Fist of Stone) that I'd like, so I'm leaning towards a caster that uses the Sorcerer spell list. I could be dissuaded from that, but that's what I'm thinking of at the moment.

, I'd also like to be able to wear armor, so that I don't have to pump Dex for good AC, letting me get a better Str/Con/Cha. I looked at Battle Sorcerer, but only 1 spell known for the first two levels seems awfully restrictive. At the moment, I'm considering focusing on spells with no somatic component, trading the familiar for Metamagic Specialist (no increase in casting time for metamagic spells) and taking Still Spell around the time I get second level spells.
Any thoughts on how to improve that?
