This is something that's definitely really cool - since the new series of ninjas pretty much dominate mystic knights in every way (aside from leader skill). Ultimate evolutions also typically do carry some crazy new leader skills too - so maybe we'll see some really neat new things to keep them viable.
There's also the chance that they'll get a new active skill, so there goes your max skilled knights...
Also just had this happen to me. If I had just a little more damage...
