I've left my original f/b below.My point is the matching of boosters needs to be introduced.I have spent money on cards but want to use them against similar levels.I constantly have higher boosters or lower,never similar level.Resonding by saying contact the developers is not an acceptable or reasonable response.Either offer credits or change the format or i'm off. The game is great but the matching is ridiculous. You should be put against players of similar level but using the same boosters.
