Here we have a collateral rarity phenomena: Many of the usual top rankers would mind less about the SED than about how exclusive is the card (E.G. how many people has June Akagi (Elite), while she is N rarity). As we have seen in the last faction wars, the Librarian R card is much more exclusive than the winning SR Nurse card. So many people will aim to the expected losing faction. Still not the most, high SED cards are tasty if you are not already loaded.
