Evolve Snorunt. Snorunt can be found in Shoal Cave Ice Room
You can find wild Electabuzz on Route 222 and you get the Electrizer at the Valley Windworks and can be held by Wild Electabuzz.
You cant in the wild but i think you can get a misdreavus in the lost tower after 8:00pm and evolve it.
For Mothim, you must evolve it because it is not wild. Same for Wormadam
You have to be able to trade scyther holding metalcoat to evolve it unless you use an AR to make it possible to find scizor in the wild
You can catch wild bonsly in the grass around Hearthome City, and it will evolve into sudowoodo at level 24.
