Mamoswine or Froslass

Current team:

• Infernape
• Staraptor
• Magnezone
• Umbreon
• Shellos (to be Gastrodon)

Can’t decide whether to put in mamo or lass in for my ice type. I have a pretty glaring fighting type weakness with mamo, but I guess it would be useful for Volkner.

What do you guys think?
