I'm looking for an anime which I saw like 12 years ago. The only thing I remember is that it was sci fi show where humans were fighting with some kind of aliens which had mothership floating above earth. I only saw part of the episode in which humans attacked the mothership. Two teams began assault inside the ship and their callsigns where playing card names like queen of diamond. That's pretty much it. I know it's nothing, but maybe someone would somehow take a lucky guess.
