You played well but you must remember some moves are good in singles only. Destiny Bond is a good move in Singles but it's not worth in Doubles, I was kinda surprised that you went with that, I hate players who just abuse that to just get a simple faint. Your Aegislash could have taken Gallade out with a Shadow Ball, it even out sped even though my Gallade was scarfed. Also Protect is the move you want to have because it gives you a scouting tool and prevents double targeting. Also speed control is very important, you had Thunder Wave but a lot of pokémon are immune so Tailwind or Icy Wind is the move to go with.
