SpDef: 95

for Glaceon those are its basic stats, below is its weakness.
Fighting, rock, steel, and fire, those are the most effective ones, against him/her. But he also has a lot of move pools he can learn and by that i am talking about learned moves and tms and such, so he can cover his weakness.
Mamoswine
HP: 110
Attack: 130
Defense: 80
SpAtk: 70
SpDef: 60
Speed: 80
His many weakness are: Fighting, water, steel, grass and fire. You can also teach him so moves to help him out.
If you look at both of their stats, Glaceon would be good for using special attacks, and getting attacked by special b.c of its stats for sp.at and sp,def, while Mamoswine should be used for attacking with physical and defense against physical attacks.
