you can scry shaper guardian maps

Despite them being "uniques" on the atlas page (you cannot scry other regular maps onto them) if you get the seer as the mirage, you can go inside and scry the div cards from a shaper map onto a regular map

here's some picture proof

edit: looks like a visual bug?, relog removed the purple link

I was able to scry Forge of the Phoenix onto Pit, then as soon as I beat the Shaper the scry line disappeared and Pit reverted back.
