You have insane stats. Good rolling.
Hexblade is any non-good, so it's technically not evil per se.
It has Concentration as a class skill, which Master of the Unseen Hand requires.
It has Arcane Resistance, granting you your CHA to Saves against spells. Oddly enough, even divine spells, despite the name.
It has full BAB, which I'm sure can help for something, somewhere, somehow.
It gets Mettle, which is a good thing. Very good.
And it has that funny little curse, if you feel like de-buff lite.
For a ranged build, using TK with objects, Dragon Magazine is your friend.
The Compendium for Dead Eye and 310 for the Targeteer variant fighter.
2x Dex damage for each ranged attack withing 30'?
Nice.
Paladin is always good for some more Cha to Saves/AC (sub. level).
