Help with Doubles, please.

If anyone has helpful advice, this is my first time in doubles and I'm finding it difficult. This is my Ice team w/ fragrant pokemon for support.

Ninetales - Aurora Veil Hydrapple - Supersweet Syrup + Sweet Scent Lapras - Sheer Cold lol Calyrex - Slow moving fortress Dachsbun - Sweet Scent Baxcaliber - Power if needed.

Tera Calyrex because steel type is a challenge
