You need the national pokedex to go to the Survival Area. go to the route to the right (East) and to the north you'll see a place to use rock climb. use rock climb and head east and you'll see a small house. This is the place where someone will teach your Pokemon moves if you have color shards (found underground). Tell the person to teach your Poliswine AncientPower. Now all you have to do is make your Poliswine level up. You can battle with it or use a RareCandy. Your choice. It doesn't matter what level it is. you just have to make it level up. Have fun with your new Mamoswine!
you cant unless you migrate :)
You have to talk to the Move Tutor for Piloswine to relearn it. An alternative is to breed a Swinub with Ancientpower as an egg move or to take it to a Move Tutor.
sadly......no it's level will be to high to get it higher
A girl in Mistraltion City will teach your Piloswine Ancientpower (or any other move by that matter) in exchange for a Heart Scale. Once Piloswine knows Ancientpower, level it up! You got yourself a Mamoswine!
