>>55712126GTS is usable in X/Y as long as you dont trade for the hacker pokemon which are all shinies with fake information (like quit the gts as it's gender) those will crash your game but the normal trades are fine, I managed to get every trade evolution last night for my dex on X
I'm a bit bummed I probably wont be able to get the shiny charm until the pretendo servers are back up tho since I still need a lot of legendaries and some version exclusives since I only have X and OR currently
>>55712188Those are hacked and will crash ur game if u try to trade with them
