So I ended up getting a bunch of the Ultra Pro sleeves in various colors to match the Unfair decks and sleeving up around 350 Unfair cards. Fortunately, some of the other folks in my game group helped. I am pretty pleased with the sleeves. In addition to protecting the cards, the game played more easily: less time spent shuffling and picking up cards. (I just made everyone slide shuffle instead of ripple shuffle and that worked fine.) I also sleeved up Clank! and bought some sleeves for my new copy of Terraforming Mars which arrived today.
