Jermlaine Swordsage with Shadowblade and Intuitive Attack for WIS to attack and DEX to damage. Since all of their stats are crap except for +6 DEX & WIS, might work. Though they are tiny, so you'd need to actually have them in the square of whatever you're attacking.
Though a thousand little rat-like Fey swarming all over someone, and punching them over and over is kind of amusing.
