Why do I always struggle choosing sweepers? [RMT]

[Johnzaloog]

Here I am, once again, for a RMT. I've been messing about with theories for a while now, but I have a combo of walls that seem to work well together, it's just choosing my main sweepers, it's a pain. The sweepers that you see have just been made up, but will probably be changed.

At a glance:

Forretress
Leftovers
Sturdy
Relaxed/Impish (depending on gyro or EQ)
252HP/162ATK/96DEF
Gyro Ball/Earthquake/Stealth Rock/Spikes/Toxic Spikes
Stealth Rock/Spikes/Toxic Spikes
Rapid Spin
Explosion

My lead and main physical wall/sponge, sets up rocks/spikes and retreats for when I need spinning. Explodes when done.

Vaporeon
Leftovers
Water Absorb
Bold
188HP/252DEF/68SATK
Surf
Ice Beam
Wish
Roar/Yawn

I needed a wish passer and a phazer. I knew he was a good passer and I wondered if he could phaze. I saw yawn and it said it's mediocre at best but I really need one.

Heatran
Choice Specs
Flash Fire
Modest
40HP/252SATK/216SPD
Fire Blast
Earth Power
Dragon Pulse
Explosion

What can I say, If it can attack, It blows a hole in whatever it sees. He can take a hit too, and he covers forretress' lone weakness well.

Celebi
Leftovers
Natural Cure
Bold
252HP/220DEF/36SPD
Energy Ball/Grass Knot
Leech Seed
T-Wave
Recover

Just like when there's smoke there's fire, where there's heatran, there's most likely a celebi. She can take a few hits with seed and recover, she slows down sweepers nicely, getting rid of gyaras is always a plus. But I was unsure of maybe using Energy ball instead. It's your call.

Weavile
Choice Band
Pressure
Jolly
40 HP/252ATK/216SPD
Ice Shard
Pursuit
Brick Break
Aerial Ace/Night Slash

I've never used him before,and I don't know if he fits this team. He's a had hitter, and this team needed some speed. Shard revenge kills garchomp, if vapes is down, pursuit gets rid of thos frail psychics, do i really need to explian the rest?

Electivire
Expert Belt/Life Orb
Motor Boost
Mild
76ATK/252SATK/180SPD
Thunder Bolt
Flamethrower
Hidden Power Ice
Cross Chop

He's a late game/mixed sweeper. Electric immunity helps and so I thought I'd use him, but again, not sure.

Help me out please.

I would seriously consider something that can kill off your Fighting type pokemon like CB Hera or SDLucario which give you problems. Pokemon such as a Defensively Bulky Gyarados, Dugtrio, or Gliscor would help you out. Sleep Talk Gyarados could work, giving you a Ground Immunity and being Bulky Enough to take CC and Megahorns, letting Foretress take the Stone Edge if you can predict right. Dugtrio almost ensures the kill of it, and other things like Magnezone and Tyranitar too. Gliscor is just the real counter, which takes every on Heracross set.

Vaporeon is the only thing that keeps you safe from a Mamoswine, as it KO's 3 of your pokemon easily. Bronzong, Cresselia, and Skarmory counter Mamoswine, as long as it does not have Blizzard, which hurts Skarmory. Bronzong can come in handy with Heatran, both covering the things that they most fear. Skarmory can take Ice Shard, is Immnue to EQ, and takes Stone Edge with easy, and you either set up or Whirlwind it. I would replace Electivire with it.

I do know, that if you do make this changes, you will lose all your sweepers, and make it a very defensive team. If you really want some speed, I would replace Choice Specs on Heatran with a Choice Scarf, it's very effective, and still helps you out, considering you have a Celebi.
