So, #216 is Wynaut, which you can get by dropping off a Wobbufett (holding a Lax incense that can be bought at the Hulbury market) and a ditto at the nursery. The egg you'll get from the worker will contain a Wynaut, but the Wobbufett has to be holding the lax incense, otherwise you'll just get another Wobbufett.
#276 you definitely have to trade for, so I can help you out with that. Just make sure you have a Shelmet! I can also trade you a Wynaut if you don't feel like going through the breeding process :)
