I guess I'll need to fill out your character sheet for every type of clone used? Well, it wouldn't be too hard to alter the sheets. The standard ones are in the lower intermediate, the other halves in mid intermediate, the original Evvie (I won't use her demigod form, which is high), and the elite clones are higher intermediate. The clones with the dragon half removed will be low, but I doubt they will do anything. The 3/4th dragon clones are low on the high rating. So for a simple list from strongest to weakest (and amount of >'s for the difference in power):

Demigod Evvie>>>3/4th Dragon>Original Evvie>Elite Clone>>Other Half Clone>Standard Clone>>>Only Human Clone

There are also some one of a kind clones that can shake things up.
