I was fascinated by the mutation pieces because they were said to be a bug in the system, and they allow for a Master to almost cheat in a way by recruiting a character that requires a lot of pieces by using a piece that require less. I would think that if I were Issei, and I got a mutation piece which is rare to acquire use it on someone like Tiamat for your Peerage because you can recruit her, and you don't have to use your other pieces, and this is the thing I love about the Peerage system because you analyze and find out what characters fit your style of leadership, and what type of techniques that they use because you have to balance it out to make balanced because if you have a team of Power types they can be demolished by a team that uses Techniques types the aspect of strategy in the Peerage system always fascinates me since I play chess myself.
