Sweet. Here's my proposition: I need quite a few of my Pokemon cloned, so I am requesting that you clone them for me. Of course, chances are that you aren't going to do it for free. In return, you would get to keep a clone of the Pokemon that I give you (basically, if I gave you a Celebi to clone, you would clone it twice, then give me back both the original and a clone while you would get to keep a clone for yourself). This would also extend to held items (if Celebi's holding a Masterball when it gets cloned, you would get to keep both one of the Celebi clones and the Masterball).
Well. Does it sound like a good deal?
