While people are talking about Flygon, I think he needs something to make him better. He is hanging on to his OU status by a thread because of bad stats. A base 80 dragon priority would be killer. On an adamant choice band set, it would do more than adamant choice band Scizor's bullet punch. True steel hits more things super effective then dragon, but dragon is resisted by only steel. If they aso gave Flygon the fire version of aqua tail, with Fire Tail and EQ, nothing could safely switch in. It would come down to predicting what attack Flygon would use. With a good prediction, you could easily send some in. With low stats and the fact that it is counterable, I don't think it would be broken, it would just up Flygon's usage.
