That's completely irrelevant. If you read my proposal it says that it would be up to the SUBMITTER to decide what was/wasn't competitive on this Pokemon. They would have 6 choices (outside of TM/Tutor moves) for competitive moves. Really if you can't choose which 6 moves are the best on a Pokemon, not including TM/Tutor moves which include some of the best moves around, then you shouldn't be submitting a movepool.
But lets say, taking the Kitsunoh example, someone posts a set of moves without Ice Fang claiming it isn't competetive, and it wins. Ambiguous moves such as that cause a problem when someone submits a movepool with Ice Fang in it. Can that movepool be allowed? Do we go by the opinion of the original set of moves? It could be argued if Ice Fang is competetive on Kitsunoh or not, leaving issues if it is allowed or not.
