Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Ohhh ok, I know what the problem is. The Galileo Rayquaza is tradable, it's just that I can't receive it in my copy of Y because Dragon Ascent isn't in the programming. I'll move the Zapdos over to my copy of AS and I think the trade will go through
I think you may have traded me the wrong Rayquaza then, the IV checker says that it only has Def, SpDef, and Speed maxed and the hidden power checker says the hidden power is dragon. Did you by chance reset two different Jolly Rayquazas?
