I cant figure out how to get a snivy to learn iron tail. I know that it involves chain-breeding but i cant figure out how to do that. Can someone tell me how to do it and the order of pokemon I need to chain breed

You may also be able to do one of these:
catch an boy onix and raise it to teach it iron tail then breed it down with a female picachu.when you have a male picachu with iron tale let it have an egg with you serperior or whatever you are using to get a snivy and there you go
