i have no problem with it, but: it should follow the same rules for static artifacts for the most part. you will need to have the appropriate number of points in order to wield an artifact of the corresponding CMC, and rare and mythics will need to be bought separately.
I didn't realize how disorganized I am...
I thought I had more questions than that, but forgot some and common-sensed my way to answers on others.
EDIT: Btw, if you keep this as the discussion thread, please feel free to change my first post however you want ;).
