Your Aegislash would be better off with Shadow Ball or Shadow Sneak and give Brick Break to Weavile (if you're using it to remove opponent's Reflect/Light Screen).
Other than that, it looks fine if it's gonna be a Toxic staller, but it would mostly work on Physical enemies.
Your Weavile has a strange moveset with Aerial Ace. Maybe you can give it Fake Out or Ice Shard instead of Aerial Ace and Brick Break instead of X-Scissor. Brick Break is strong against other Dark Types, Steel types and Knock Off STAB is already strong against Psychic types.
Its EVs should also max attack since it's already weak. It won't survive many attacks and should act like a threat that does as much damage as possible.
I think Exploud has an okay moveset, but you could try Icy Wind instead of Blizzard. It slows down the opponent's team, hits all opponent's in Doubles and Triples (Depending on Exploud's position).
You could also replace Focus Blast with Flamethrower or Fire Blast, but it's up to you.
I think you should give Breloom Spore. One opponent sleeping is always a very good advantage. Drain Punch would also work much better than Superpower, it doesn't drop your Attack and Defense when used and you'll heal with Drain Punch.
Facade is alright, but maybe you can consider Substitute for better stalling.
Arcanine could be better off with Iron Head or Wild Charge instead of Close Combat since you already have lots of Fighting type moves. Iron Head pressures and kills Fairy types easily (except for a few) and Wild Charge would give you an Electric type move since you don't have one. Good coverage, too. Intimidate as Ability is also a much better one, especially in Doubles and Triples.
Alakazam's moveset is just fine IMO.
About your team's EVs, maybe you should change them up to fit their roles more. For Example Alakazam needs max special attack to hit hard. It doesn't need defense EVs. If you want to guarantee to let it live a hit, use Focus Sash.
Use items well in League.
