Please Help with my first competitive team

[Poog]

Hi! Last summer I started getting into competitive pokemon and I bred/trained the pokemon and aquired everything but once school started I had no time to play, and in that time 2 of my core pokemon had been banned :( but I figured should try to make a new team and get back into competitive pokemon. I know the basics such as , breeding, ev/iv, and stuff like that, I do not know good team building ideas and stuff like that. My team so far is: (I would like to keep volcarona and breloom but other than them I can use any OU pokemon)
Volcarona (M) @ Life Orb
Ability: Flame Body
EVs: 136 HP / 252 SpA / 120 Spe
Modest Nature
- Giga Drain
- Fiery Dance
- Quiver Dance
- Bug Buzz

Breloom (M) @ Toxic Orb
Ability: Poison Heal
EVs: 56 HP / 252 Atk / 200 Spe
Adamant Nature
- Seed Bomb
- Focus Punch
- Substitute
- Spore

Raikou @ Choice Specs
Ability: Pressure
EVs: 32 HP / 252 SpA / 224 Spe
Timid Nature
- Thunderbolt
- Volt Switch
- Extrasensory
- Shadow Ball

Skarmory (M) @ leftovers
Ability: sturdy
EVs: 252 HP / 252 Def / 4 Spe
Impish Nature
- Roost
- Stealth Rock
- Whirlwind
- Brave Bird

Im not 100%sure of the next 2 and would take any suggestions on them!

Azumarill @ Choice Band
Ability: Huge Power
EVs: 172 HP / 252 Atk / 84 Spe
Adamant Nature
- Play Rough
- Ice Beam
- Aqua Jet
- Superpower

Garchomp @ Life Orb
Ability: Rough Skin
EVs: 4 Atk / 252 SpA / 252 Spe
Naive Nature
- Draco Meteor
- Earthquake
- Fire Blast
- Stone Edge

Any suggestions or help making teams or being aware of the meta or literally anything would be helpful! That is the team I have been practicing with on Smogon and it has about a 40% win. My only concern is that it has no response to hazzards, plus with the loss of greninja I am losing a lot of type coverage. PLEASE HELP!!!!!

Chain chomp is really a thing of the past Imo unless I guess if it is mega chomp. I think stealth rocks on chomp would be something you should consider . You could go for rocks/outrage/earthquake/swords dance with lum /jolly max speed and max attack or if you want a more defensive chomp you can use 52 HP / 164 Def / 76 SpD / 16 Spe impish with like dragon tail/eq/rocks/ endure or fire blast. Endure allows you to achieve nice damage on physical attackers and the spread is so that you can survive an hp ice from thundurus. Skarmory should have spikes imo since if you go according to my suggestion you already have it on chomp, and skarm's bulk allows it to spike nicely. Iron head is also a good option over brave bird to hit diancie nicely, tho specs tbolt from raikou does a ton to it, just FYI.

You should also consider starmie over azumaril, since you are very keldeo weak right now and offensive spinner starmie puts in a lot of work in terms of offensive pressure. You could go for like life orb thunderbolt/ice beam/hydro pump/rapid spin or bulky reflect type or the scald psy shock recover rapid spin set, up to you. I think the offensive bolt beam set would be nice here.

Breloom and volc really compound your weaknesses and raikou doesn't necessarily stop talon flame, since flare blitz can ohko with minimum prior damage.
O and fire blast>fiery Dance on volc, since the extra power is much better than the chance of spa increase. Since you are not usi hidden power ground you should be careful about not setting up if the opposition still has heatran alive, and it would be really good if you can apply pressure and kill it off asap.

Hope I helped.


EDIT: even though you may not use azumaril since starmie does a better job here by spinning etc, pls don't use ice beam on band azu lol Or any azu for that matter :( It uses waterfall along side Aqua jet to hit harder.
