Hi Don,
I've been thinking about it since no one's done it before (as far as I know).
Also, I think the uncut sheet of a transformation deck would be higher on a desirability scale than other uncut sheets. To this day, I still get inquiries from people on how they can get a Curator uncut. Out of the 20 or so different uncut sheets that HOPC sells, only 3 have sold out, and the Curator uncut sheet was one of them.
Their popularity is all the more reason why you wouldn't need to run an early bird to get them sold out, fast. It's not like the demand for these uncuts will be soft, now is it?
Unless you were planning to offer a LOT of uncuts, I'd reserve them for regular sale.
Consider offering people a poster with the image of the uncut on it for the Curator deck. It's not the same as an uncut, but it's the next best thing and would cost less both for you and the customer. Win-win, right?
If you wanted to make a special early bird without giving away your best goodies, make a poster of the Clipped Wings uncut as an early bird tier with a deck - it would be a nice extra. You could make the poster smaller than normal size so it's inexpensive and at the same time cool looking.
