Answer 1

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

Ability: Levitate

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.
