Chimcharlk

Need help So i was trying to put my raichu in my pc so i could go do the munchlax resort fight, but i accidentally released them. I was also on mobile, so when i went to go to this website to find out how to get him back it closed. So i also don't have any information besides maybe its moveset and OT. I know this isn't probably enough to do anything but i thought i should try anyway. Edit: gold server
