Collectible Card Game Headquarters

Has anyone played with any of the custom minis (so anything from Witching Hour, Twilight, or the general custom folder)? These have seen very little play testing (although Scud-O's sets may have, I'm unsure) so I'm wondering if any are severely over/under powered.

A bunch of cool new customs will be in the next release too which will be out soon.
