Newbies first team!

Hello there,

   I've never really battled competitively, I've always been a casual player since the Red and Blue years, but here lately I feel like I want to try to get into the meta. I've done a little bit of research and I feel like I put together a good competitive team. I haven't really raised the team yet, but I just want to get some advice.

Charizard Y
 Timid Nature
Blaze
  252 Spd/ 252 Sp Atk/ 4 Sp Def
   Fire Blast
   Solar Beam
   Focus Blast
   Roost


 Slowbro
   Bold nature
Rocky Helmet
   252 HP/252 Def/ 4 Sp Atk
   Scald
   Fire Blast
   Slack Off
   Psyshock
   
Amoongus
  Calm Nature
Black Sludge
  252 HP/ 252 Sp Def/ 4 Sp Atk
  Spore
  Giga Drain
  Sludge Bomb
  Hidden Power Ice


  Gliscor
  Impish nature
Toxic Orb
  TBD
  Knock Off
  Toxic
  Protect
  Substitute

  Excadrill
Life Orb
  Adament nature
  TBD
  Earthquake
  Iron Head
  Rapid Spin
  Stealth Rock

  Keldeo
  Everything TBD



  I just wanted to get thoughts on this team. I think it would be a good team, but then again I haven't really battled competitively yet. Any constructive criticism is greatly appreciated. Thank you!

This is a pretty good team on klefki your gonna want a defensive set with status moves probably toxic and spikes also protect or subsitute and give it an item like leftovers so that it can stall. And are you up for a battle somewhen cause that could help test the team out

So far it is a pretty good team like Ikey said.

I am considering taking Keldeo out for something else, because I didn't notice I have four pokemon weak to psychic, but I know you can't make a perfect team.

oh woops just realised you put keldeo not klefki ignkre my advice

Maybe put in a dark type like honchkrow to replace keldeo with that physical role.

But there aren't 4 pokémon weak to psychic, only two. Two other pokémon resist it.

Charizard
modest Nature
Item: Charizardite Y
Blaze
252 Spd/ 252 Sp Atk/ 4 Sp Def
heat wave
Solar Beam
Air slash
dragon pulse

thats the set that I would normally use with mega charizard Y it works affectively

Both Charizard sets are good imo.

Shoot. Idk what I was thinking about the typing. I'm not 100% on the Charizard set yet, would the speed boost be worth the timid nature or should I go for more power?

I would go for speed since today's meta is heavily relied on speed unless you have some Pokémon that can paralyze, but looking at your team you don't have any.

Thanks for the input everyone! I've made some slight changes and I've finished breeding most of these.
