Yes this is still a thing. I've been trading quite a lot recently.
First, to your request, this is a TRADING thread though, so you shouldn't be asking for someone to donate a mon for you. Instead you should be offering something from your mons for the Exeggcute and Clauncher. You can offer ANYTHING, just anything what you got or just go grap an extra pokemon if you don't have any spare.
Second, i don't have Clauncher but i can offer you a trained Exeggcute in a trade for something. I can even make it 5-6sh IV if you got anything interesting mon to trade it for.
Third, raising a mon when you've finished ep15 is damn easy. If you have an exp.share it's easy to just grind in a Opal Ward Grand Hall against weekly trainers, or the Clown in Agate Circus. You can easily raise lvl 1 mon to 50 level in 10-15mins. And if you got a Lucky Egg you can start using it when your mon is enough strong to swipe anything by itself.
EDIT. Actually, i would like to have your Clauncher in trade for trained Exeggcute (if you only have 1 Clauncher just go and breed it)
