Go to the move tutor in Pastoria city and teach Pilowsine ancient power at somewhere around lvl 35
Probably Weavile, Glaceon, or Mamoswine.
You must learn it Ancient Power and then you level it up. Then it evolves into Mamoswine.
I'd say Garchomp, Gallade, Magnezone, Electivire, Magmortar, or Mamoswine.
No Mamoswine is not a legendary Pokemon
that depends on what moves you teach it! =)
You must evolve a Piloswine to have a Mamoswine.
The code for Mamoswine is POKEMONDOTCOM.
swinub evolves into piloswine at Level 33 and then it evolves into mamoswine when it gains a level after learning ancient power
You can't because mamoswine was made in the 4th generation games diamond and pearl and platinum it never existed in leafgreen.
It depends on what level they are on. But it looks to me like they are good. At the very least, you have a good variaty of pokemon.
In Pokemon Diamond and Pearl the Gym Leader Candice has; Snover, Sneasel, Medicham and Abomasnow. In Pokemon Platinum her team is mostly different instead having; Sneasel, Piloswine, Abomasnow and Froslass. She can be rematched in Pokemon Platinum with an updated team which is; Weavile, Mamoswine, Abomasnow, Froslass and Glaceon.
Mamoswine doesn't evolve either way because it doesn't exist in Pokemon LeafGreen. It evolves from Piloswine who evolves from Swinub, but Piloswine can't evolve into Mamoswine in LeafGreen.
