Sets have been using the WUBRG order for a while. However, many older sets have a different order which many people don't know. Heck even Gatherer does it WUBRG for all sets.
However, since I own an actual Mirage binder with the pages I know the order of Mirage itself. Especially cause those pages are numbered.
I would love to be able to change it per set so the binder view matches what is in the binder.
This is the order:
Artifacts
Black
Blue
Coloured (aka Multicoloured)
Green
Land
Red
White
Alright I understand, looking forward to it once you get to it
This is quite complicated for now but I added the idea on my todo list
