If you post renovation you can't get Azurill by yourself until next episode, tropius you can catch wild in the jungle next to Beryl ward, heliolisk is a low chance encounter but is only found in dessert after restoration think Syther but dessert can also be found in mirage tower dessert but not when it's barren, emolga is wild morning and day in Jasper ward grass, out of luck on whismur line as well currently
