Clonns as a concept are amazing. While it does take a little more work than usual to figure out the maths of your character's abilities, the end result is frankly amazing mechanically. You are at the very least okay with a wide variety of skills, and the clonns' various other features compliment a wide variety of different classes, though I am partial to bards. I also feel the listed feats do a very good job of enhancing the concept even further.
