Hello guys and gals. I've made this team for a few weeks now. I've been using it and it has been working kind of well. Even though I think it is a decent team I'd like to get advice from others, since we all have different ideas and strategies.
THE TEAM AT A FIRST GLANCE
The Team
Steelix (F) @ Steelixite 
Ability: Sturdy
EVs: 252 HP / 96 Atk / 76 SpD / 84 Spe
Adamant Nature
- Earthquake
- Toxic
- Heavy Slam
- Stealth Rock
Steelix will be my bulky sweeper. It has Toxic so that I can deal growing damage to my opponent every turn while dealing damage with either Heavy Slam or Earthquake. Stealth Rock is an hazard so that I can either deal damage to other Pokemon or so that I can get rid of sturdy. Earthquake is one of my stab moves together with Heavy Slam. I preferred Heavy Slam to Iron Head since when Steelix mega evolves it gets heavier and because Heavy Slam has better accuracy than Iron Head. THE TEAM AT A FIRST GLANCE
The Team


Ability: Sturdy
EVs: 252 HP / 96 Atk / 76 SpD / 84 Spe
Adamant Nature
- Earthquake
- Toxic
- Heavy Slam
- Stealth Rock
Ability: Water Absorb
EVs: 252 Atk / 128 Def / 128 SpD
- Drain Punch
- Earthquake
- Toxic
- Scald
Ability: Levitate
EVs: 252 HP / 128 Def / 128 SpD
Sassy Nature
IVs: 0 Spe
- Toxic
- Protect
- Gyro Ball
- Earthquake
Another bulky-mon. Bronzong has the Toxic-Protect Strategy which is very useful unless I'm facing a Steel type or a Poison type, though Poison types can be dealt with fairly easily. Gyro Ball is the stab move. Having pretty low speed Gyro Ball does some nice damage on the opponent. Earthquake is used to cover Bronzong's Fire type weakness.
Ability: Flash Fire
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Heat Wave
- Nasty Plot
- Dark Pulse
- Hidden Power [Grass]
Ability: Levitate
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Leaf Storm
- Volt Switch
- Trick
- Thunderbolt
A sweeper/troll. With Trick I can give Choice Specs to my opponent making it only be able to use one move and with the chance of me getting a nice item in return. Leaft Storm will deal great Stab damage and if I want more power I can just use the Choice Specs. The same goes for Thunderbolt. A way of switching and dealing damage (In case I chose the strategy with Trick) is Volt Switch.
Ability: Mummy
EVs: 172 HP / 84 Def / 252 SpD
Bold Nature
- Will-O-Wisp
- Protect
- Shadow Ball
- Haze
This is one of my favorite mons due to it being so bulky and useful. With mummy I can get rid of my opponent's ability. Then I have my Will-O-Wisp-Protect combo. With Haze I can stop my opponent from setting up, though it would get rid of the burn. Shadow Ball is my dealing damage move. The only weakness I see on this mon would be a Baton Passer or a Normal type.
I'll gladly appreciate any ideas on changes that I could do on this team to improve it. Thank you for reading. I hope you have a fabulous day.
