the seventh gym leader, Brycen, has the following team:
Vanillish Lv 37
Ability: Ice Body
Moves: Acid Armor, Astonish, Mirror Shot, Frost breath
Cryogonal Lv 37
Moves: Reflect, Aurora Beam, Rapid Spin, Frost Breath
Beartic Lv 39
Ability: Snow Cloak
Moves: Swagger, slash, Brine, Icicle Crash
He's basically a more pathetic version of Pryce. Ice types can be countered with fire, fighting, rock, and steel type moves.
Beware as Ice types are strong against grass, ground, flying, and dragon types.
