New OU team, any input really appreciated.

The Team​

My Thought Process​

This team started as an attempt at a Mono-Ground team, but as you can see it quickly became something else. I started with Hippowdown because she is arguably one of the best walls in the game in my opinion and she also has a pretty useful attack in case she gets taunted. Once I decided to make a normal team I started to look for strong Pokémons that I haven't really used before (I like variety in my teams) so I decided on Bisharp who is a we all know one of the top tier threats, since the main reason for hi sudden increase in usage was Defiant+Defog I thought on trying to force my opponent to use defog so I can bring him in, enter Galvantula and her sticky web.

At this point I had a really strong physical attacker and another fairly decent special attacker and since I always liked Mixed Attackers for their versatility I looked into them. Mega-Garchomp is a pretty scary Pokémon on his own right, but it suffers a lot from the drop in speed, but hey I have Sticky web on the field so he can come and wreak havoc with some impunity.

Continuing with my mixed attackers I decided on mixed Thundurus-I, why? Because nobody expects it! Most people see Thundurus I and send their special wall who then get's smacked with a Hammer Arm to the face or a priority T-Wave, and if I still have sticky web on the field it sort of compensates the speed drop. Finally I was a little tired and decided to go with Keldeo because I've always liked the pony and he is pretty threatening with specs.

A more detailed look into the team​

Hippowdon (F) @ Leftovers
Ability: Sand Force
EVs: 252 HP / 252 SDef / 4 Def
Careful Nature
- Slack Off
- Earthquake
- Stealth Rock
- Toxic

Pretty standard mixed wall set, nothing out of the ordinary except for Sand Force instead of Sand Stream because while two other members of the team don't mind the sandstorm, 3 others don't like the extra damage due their inherent squishiness. Earthquake is to avoid becoming Taunt bait and to punish those pesky steel types who want to switch into a toxic.

Bisharp @ Life Orb
Ability: Defiant
EVs: 252 Spd / 252 Atk / 4 HP
Jolly Nature
- Sucker Punch
- Iron Head
- Knock Off
- Swords Dance

What can I say about this set? It simply tears through teams with Stab Knock off, ideally he wants to switch in into a defog for the Defiant boost and if this happens he will most likely force a switch giving him a turn to set up a SD and destroy opponents. Talonflame is obviously something to be aware off being able to OHKO with Flare Blitz, but Sucker Punch is also a OHKO (after rocks or a Defiant boost) so it really comes to prediction.

Garchomp (F) @ Garchompite
Ability: Rough Skin
EVs: 240 Spd / 16 Atk / 252 SAtk
Hasty Nature
- Swords Dance
- Draco Meteor
- Poison Jab
- Earthquake

Chainchomp, because why not? Sword Dance previous to mega-evolve and wreck faces with the appropriate move, obviously you only want to bring her in when fairies are off the field (Bisharp is pretty good for that), but in case it isn't possible you can fall back on Poison Jab which should deal with every fairy in the tier bar M-Mawile and Klefky (which are taken down with Earthquake in any case). Since M-Chomp forces so many switches it should be easy to get a turn to set up SD. He does have speed problems so getting Sticky web is a priority.

Thundurus (M) @ Life Orb
Ability: Prankster
EVs: 72 Atk / 184 SAtk / 252 Spd
Naive Nature
- Thunder Wave
- Thunderbolt
- Hammer Arm
- Hidden Power [Ice]

Thundurus-I job is to be incredibly threatening and/or annoying, the mixed set allows for both with Hammer arm allowing to deal with pokémons that he shouldn't be able to, like Blissey (which he 2hKO), Thunderbolt+HP Ice is pseudo boltbeam coverage. Prankster+T-Wave is to be annoying, pretty standard but dam useful.

Galvantula @ Life Orb
Ability: Compound Eyes
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature
- Sticky Web
- Thunder
- Bug Buzz
- Energy Ball

I'll be honest, the main reason Galvantula made to the team is that she is arguably the best sticky web user, but therefore I should aim to get the most out of this cute spider Thunder+Bugg Buzz is a staple on Galvantula due stab+high speed and SpA; I choose Energy Ball due bulky ground/water types who I can't really touch otherwise. Max Spd EV's are used to maximize the opportunities to set up Sticky web.

Keldeo @ Choice Specs
Ability: Justified
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature
- Hydro Pump
- Icy Wind
- Secret Sword
- Hidden Power [Ghost]

To be honest I don't have much to say about Keldeo, his job is to hit as hard as possible and he does that pretty well, my only issue with him is that I'm not really sure if HP Ghost is the best option, I've considered HP fire but... I don't know I feel HP is just weak in general and only should be used for coverage.
