2 rulings from Wizards of the Coast
- 18 June 2021You 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.
- 18 June 2021Even 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.
