you can get it from pokeshop and go to other items and then go to the last page of other items and there you can find rare candies. and if you want legendry Pokemon then add tatya in your account and he will give you any legendry Pokemon if you give him 5 lakh ic coins
Snivy, Tepig, and Oshawott are the starter main Pokemon. The legendry Pokemon is Reshima. Hope I have helped.
