I don't know if there is a way, but I would like to search in the marketplace what characters I don't have ignoring evolution. Meaning that if I have ydiane lvl 3 and search, i don't want to see ydiane lvl 1 or lvl 2 in my search. this is easier way to get at least one copy of the missing characters without having to remember what I already have in my collection. I am new player and for now I try to have at least the max level of each character before I start getting all upgrades.
