Hey Miss, since your PM box is still full, I decided to leave a message here. I have a leftovers, and also many other items that I can offer you, but since I am a noob, I don't know which items are more valuable for colectors like you. I have PP up/PP Max, 40+ rare candies, Black sludges, all mega Stones available in Y, a Lucky egg... Any item you would normally find during a playthrough, minus Master ball, because I spent it. I also have that event supersize pumpkaboo, if you want yet another one. Good luck on your Finals and I will be waiting for when you have time to do our trade!
Edit : I finally sent you a PM with more details
