Erm... Sky Shadow was responding to your comment,
"universe is more accurate but a different mold" -- and Universe Starscream is just a repaint of the
same mould as Classics Starscream, whereas Masterpiece Starscream is a different mould and sold in the same "Classics" style packaging as you can see
here. You may have meant to say a "different redeco of that mould", but your actual wording was "a different mould," so I can understand how Sky Shadow came to the conclusion that you may have meant Hasbro's Masterpiece Starscream.
