Also, we prefer if we know the pokemon's EV's, not stats as it means we're generally unsure what investment you put into the pokemon.
Furthermore, Fly in most (if not all) situation's is competitively unviable and Waterfall doesn't see a lot of use on Ray because earthquake is better then it in all regards other then the fact that you can hit ballooned pokemon (which isn't that much of an upside in ubers).
Finally, it'd be helpful if you describe the point of each move, the EV's, etc on your pokemon. Otherwise, again, we don't know what you're trying to achieve.
Although I know what EV's are, I don't know how to access that info. I can explain each move's purpose.
Waterfall is more or less for those pesky steel-type pokemon that resist all of he other STAB moves. Fly I use mostly to get a turn of free leftovers recovery, as well as scout moves. Draco Meteor is mostly for its STAB for Rayquaza, and its high damage. Dragon Claw rounds out the moveset for high accuracy, STAB, and it complements Rayquaza high physical attack. I'm probably going to switch Waterfall for maybe flamethrower or a boosting move, as Waterfall's only use is for steel-types. The only other things were the current level stats, because I don't know how to necessarily get that info. Sorry.
