Ok to start off, you have a massive weakness to ice. You have 3 pokemon with a x4 weakness ice and only 1 pokemon with a resistance to it. I would recommend switching out Dragonite for a pokemon with a resistance to ice. I would recommend a cloyster as you have no setup sweepers. Now I will go 1 by 1 through your team + Cloyster (just because I'm bored)
This is a very powerful mega pokemon. He has the base stat of an arceus when in his mega form, but he has a few crippling factors.
- His speed goes down in his mega form. He doesn't have much speed to spare and he loses some when he mega evolves.
- Too many weaknesses. A x4 weakness to ice and a x2 weakness to both fairy and dragon can make him useless.
- He gains a pretty much worthless ability when he mega evolves. Pared with tyranitar on a sand team it can work well, but it takes a turn to set it up if he is by himself and isn't worth it then. While other mega's get uber abilities (speed boost, skill link, shadow tag) he is stuck with a crappy one.
Now your Garchomp has a nice coverage moveset and a good ev spread so I wouldn't change anything. I'm just saying the biggest problems with all your pokemon. I would keep Garchomp the same.
What are you trying to do with it? Double team really can't be used competitively because it takes too long to set up. I like the hyper beam, pixilate, pixie plate combo. It would make it's base power 252, but can't attack next turn. I would get rid of double team and replace it with Calm mind. It is a better set up move than double team. Other than that Sylveon is good!
Inner focus over multiscale? Multiscale is worth the work! Here is how I would make a dragonite look:
Dragonite @ Weakness Policy
EVs: 4 HP / 252 Atk / 252 Spe
- Dragon Dance
- Aqua Jet
- Stone Edge
- Dragon Claw
This allows you to be hit by a super effective move and most likely live while you use a dragon dance to increase speed and attack and be able to sweep!
I honestly don't like milotic for competitive play. If your gonna use it then it looks ok, but I would replace it for talonflame! Here is how talonflame works:
Talonflame @ Choice Band
Ability: Gale Wings
EVs: 4 HP / 252 Atk / 252 Spe
- Brave Bird
- Flare Blitz
Pretty simple, just brave bird! You have 270 base power with 100 accuracy and +1 priority! Not much can live through 1 hit of that!
I usually don't bring 2 mega's into 1 team, but Charizard is a pretty cool pokemon. It does have a x4 rock weakness, but not many pokemon carry a rock type move. I don't think I would change anything!
I've been using a salamence for 3 years now and this is the best set:
Salamence @ Assault Vest
EVs: 252 Atk / 4 SpD / 252 Spe
Now Outrage is a tough move to get, so if you can't get it then replace it with Steel Wing (to take care of fairies)
Cloyster @ White Herb
Ability: Skill Link
EVs: 252 Atk / 252 Def / 4 SpD
- Shell Smash
- Ice Shard
- Icicle Spear
- Razor Shell
1 turn to set up then you have a sweeper. That simple!
Sorry if I sound mean, but I want you to realize the weaknesses in these pokemon. Hope this helps you!
