The great think about mutation is that there is one for everyone.

What do I think about that one? I found it interesting however I would not have one in my collection or work with that clown combo, just because I like my clowns and their combos to be VERY reduced so for me Blade and Enchi clown is what I chose to work with.

As far as not many people working with it, keep in mind that it is still fairly new and sometime it takes while from the moment it is first produced to the time people decide to go with the project and can actually produce one of their own.
