I've had some real success using a chariot heavy list built around the Beastlord special character. My 2150 army includes him, 4 other beastmen chariots, 1 chaos chariot, 2 bray shamans (lore of beasts ftw), a unit of hounds, 2 15 man beast herds, 4 nurgle minotaurs with great weapons, 5 chosen chaos knights, and 3 fiends of slaanesh (spawn).
On several occasions I've managed to hit several units in one turn in the rear with the herds and in the front with knights, minotaurs, or several chariots. And the fiends of slaanesh do an Awesome job of holding highly mobile units still long enough for the chariots to charge them.
