Hey everyone, this is my first attempt of trying to build a decent competitive team. I feel like it does OK, and is probably massively hindered by my poor skills as a trainer but at the same time there's probably a bunch of weaknesses I haven't realised because I haven't played Pokemon for a while.
Anyways, enough of me rambling, lets get into the team:
Donphan @ Leftovers
Ability: Sturdy
EVs: 252 HP / 252 Atk / 4 SpD
Impish Nature
- Earthquake
- Stealth Rock
- Ice Shard
- Rapid Spin
Not really sure on what to say here, but here goes. When I first thought of using Donphan, he was predominantly in the team to set up rocks, and possibly rapid spin away any hazards that get thrown my way. As I've battled people, I've learnt that he's much more useful than i first thought, as he's able to switch in on physical attacks and gobble them up pretty decently, and hit hard with a stab EQ. Ice shard is there for priority and to do good damage to flying/dragon types (as I lack coverage for those)

Chandelure @ Choice Scarf
Ability: Flash Fire
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shadow Ball
- Dark Pulse
- Fire Blast
- Trick
Chandelure is my go to special attacker but recently also became my go to choice as a lead as I can either hit hard with a stab ghost ball or fire blast, or use trick on pokemon that try setting up on turn 1. I feel like it works pretty well with Shaymin as I can absorb a fire attack with flash fire and do some damage of my own either on said pokemon or on the switch-in.

Shaymin
Ability: Natural Cure
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Seed Flare
- Earth Power
- Psychic
- Synthesis
Shaymin is here as my answer to water types for Donphan and Chandelure. If I switch in on an attack I can either hit them back with a seed flare, or synthesis to recover health from that before trying to punch holes in things. Earth power is there for steel and fire types as they're quite common switches to deal with Shaymin, and psychic is there for coverage of fighting and poison types.

Goodra @ Assault Vest
Ability: Sap Sipper
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Outrage
- Fire Punch
- Thunder Punch
- Superpower
I'm not quite sure on what to say about Goodra. This slot was originally for a white herb huntail but I couldn't utilise it too well and needed to find a replacement. After watching a couple of battles on youtube I realised that this thing is a boss and haven't looked back since.
He functions as my secondary special wall as it isn't weak to too many things, and if I predict well and come in on a grass type move sap sipper just makes this thing even more destructive. Outrage is there for STAB and good damage to everything but fairy types, fire punch and thunder punch are there for coverage and superpower is just there tbh. I never really use it so a good replacement for that would be peachy.

Umbreon @ Leftovers
Ability: Synchronize
EVs: 252 HP / 4 Def / 252 SpD
- Foul Play
- Heal Bell
- Wish
- Protect
Lemme start by saying; I absolutely adore this thing. He gobbles up everything a special attacker throws at him, and can wish-protect the health back if need be. Heal bell is there to get rid of pesky ailments such as burn on Goodra/Donphan or paralysis on anything, and foul play is there for chip damage if need be. Not quite sure what else to say as it's a pretty standard set I think...

Weezing @ Black Sludge
Ability: Levitate
EVs: 252 HP / 252 Def / 4 SpA
Bold Nature
- Toxic
- Will-O-Wisp
- Sludge Bomb
- Flamethrower
Last, but definitely not least, one of my favourite mons from day one, weezing. His role is pretty self explanatory. He tanks physical hits, and trys to get a burn or toxic off depending on what comes in to deal with him. Sludge bomb is there for decent stab damage and flamethrower is another way to deal damage to mons that have low health left when he's already in.
Thanks for listening to me talk about these pokemanz, I've been having quite a bit of fun with it because I'm still learning and stuff. Not quite sure how to end these things so I'm just gonna leave awkwardly :)
