Can you tell me the rulings for Parcel Myr?

0. Even though it is a Clue, Parcel Myr is not (normally) a token, and therefore isn't “created” when it enters the battlefield. Abilities that care about creating a Clue token, such as that of Academy Manufactor, will do nothing as Parcel Myr is put onto the battlefield. If you create a token that's a copy of Parcel Myr on the battlefield, such abilities will notice. However, if you copy Parcel Myr while it's a spell on the stack, the copy resolving will become a token, but that token is not “created,” so those abilities won't notice.
1. You can't sacrifice Parcel Myr to activate its own ability and also to activate another ability that requires sacrificing a Clue (or any artifact) as a cost, such as that of Lonis, Cryptozoologist.
