MPS promo lands are not in here that I can find.

Also, I'd like to be able to search only signed cards, altered art, or artist proof, in addition to the promo search.

Searching for all promo cards is indeed a valid suggestion, I will add a filter for that that searches in all promo editions.

Thank you.

Except you can't sort by "is promo" if you don't use that promo tag. I still want to be able to look at all of my promo cards in one search, but now cannot.
