I don't see how this refutes my comment. I didn't say Celebrations was a "b" set, I said it didn't follow the release pattern. For one reason or another it released after S8 instead of S7R/S7D and no S7a was released. Climax is a "b" set because Celebrations had an unusual release date. Climax did not.Celebrations was an "a" subset, VMAX Climax was the "b".
