>I play under my own rules with my friends. Which basically is... All OU pokemon except one, which can be a mega evolution as an Uber.
Cool! An interesting little mini tier-thing you guys have got going on. I'll give you suggestions based on these rules. Now, let's get started!
You've got a good solid Aegislash set here, but too much Steel! And you lack a special tank! So let's get one of those instead.
Sylveon @ Leftovers
EVs: 252 HP / 52 SAtk / 200 SDef
- Heal Bell
- Hyper Voice
This seemingly innocent little 'mon will annoy the snot out of your friends. Wish is always great for itself or switching to your hurt Pokemon and restoring their HP, while Protect can ensure Sylveon gets to heal. Heal Bell gets rid of annoying status conditions, and Hyper Voice is its attacking move. It also gives you a special attacker.
Dragonite @ Weakness Policy
EVs: 252 Atk / 252 Spd / 4 HP
- Dragon Claw
- Dragon Dance
- Fire Punch
>Really looking for a substitution for Dragonite, namely a sweeper.
Aww, but how come? Dragonite rocks. As a matter of fact, I wouldn't change much about him at all. Just run Fire Punch over Thunder Punch for better coverage. I luv Dragonite, but if you don't want to keep him, I can give you another recommendation-- which will be a SPECIAL sweeper. It would probably be best to switch him for a special attacker...
I would say Latios, but this is an in-game team, so I won't do that. Here's another good idea, then-- a Pokemon of the same typing:
Noivern @ Choice Scarf
EVs: 252 SAtk / 252 Spd / 4 HP
- Draco Meteor
Scarfed Noivern would give you some great Speed and power. It gets extremely powerful STAB with Draco Meteor and Huricane, while Boomburst is for good neutral damage and Flamethrower can give you the same coverage as Fire Punch on Dragonite.
Kangaskhan @ Kangaskanite
Ability: Scrappy ---> Parental Bond
EVs: 252 Atk / 252 Spd / 4 HP
- Dizzy Punch
- Sucker Punch
- Drain Punch
- Power-Up Punch
I'm looking at Kangaskhan's movepool and I'm not seeing Body Slam... Huh??.. (Learnset) Anyway, that's why I switched Body Slam for Dizzy Punch. If it can really learn Body Slam, then take your pick between confusion and paralysis! Great idea with Power-Up punch, and I like the rest of its set. Well done here.
Pretty cool Gliscor set, but if you want another special attacker, I recommend this:
Gastrodon @ Leftovers
Ability: Sticky Hold/Storm Drain
EVs: 252 HP / 252 Def / 4 SAtk
- Ice Beam/Toxic/Yawn
Gastrodon makes a great wall, and it's workable as a physical or a special attacker. I picked a special set because you could use that. Scald is great for burns, and you can choose Ice Beam, Toxic, or Yawn based on coverage, putting a timer on the opponent, or sleep/phasing. Choose between Sticky Hold or Storm Drain based on your fear of Knock Off/item theft or sucking up Water-type moves.
The rest of your team is great and I wouldn't change anything at all! I just recommend highly that you make the swaps for specially offensive Pokemon to bring more balance to your team. Have fun!
