Hi
I am here to help you out .Your team needs some primary changes and the way you gave them EVs is bad. But its ok, everyone makes it when they are new and become better so lets start here.
Tyranitar ---> Necrozma-Dusk Mane
Tyranitar can be used as a Calyrex-S counter but you used it as a Stealth Rock setter and ran a special set which is not good on Tyranitar. So NDM is a better Stealth Rocker.
Necrozma-Dusk-Mane @ Rocky Helmet
Ability: Prism Armor
EVs: 248 HP / 8 Atk / 252 Def
Impish Nature
- Stealth Rock
- Thunder Wave / Knock Off
- Morning Sun
- Sunsteel Strike
This NDM set is a Stealth Rock and Zacian counter set. You can use Knock Off against a Caly with no stat rise and full HP to KO it easily.
Ho-Oh is really a good Pokemon in Gen 8 AG but the set you use isn't that good. So,
Ho-Oh @ Heavy-Duty Boots
Ability: Regenerator
EVs: 248 HP / 8 Atk / 252 SpD
Careful Nature
- Defog
- Sacred Fire
- Toxic
- Whirlwind
This is a super specially defensive Ho-Oh set. Use this against special attackers like Calrex, Palkia, etc. And this is your teams Defogger to save you from hazards. When you see some stats rise or a tough Pokemon just use Whirlwind to get rid of them.And plus you have Toxic.
Kyogre is also a good Pokemon and I have suggested changes in your set
Kyogre @ Choice Specs /Choice Scarf
Ability: Drizzle
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunder
- Water Spout
- Origin Pulse
- Ice Beam
In my opinion Specs is great and this one is super offensive using Water spout when at full HP and rest of the moves are also good and cover most types.
Rayquaza -----> Zygarde
Rayquaza is really the most powerful in Gen 7 AG but not that much good in gen 8 AG because Zacian kills Ray easily.
Zygarde @ Leftovers
Ability: Power Construct
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Coil
- Thousand Arrows
- Scale Shot
- Rest
I have given you Zygarde coz you are wishing to have a Dragon Type.This is a defensive set and Scale Shot raises the speed and Thousand Arrows is a great move. Rest cures you from status ailment and restore HP completely.You can use it a Zacian check ,Ho-Oh Check.
Caly is one of the most powerful pokemon in Gen 8 AG. But your set needs to be changed.
Calyrex-Shadow @ Focus Sash/Life Orb
Ability: As One (Spectrier)
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Astral Barrage
- Nasty Plot
- Psyshock
- Draining Kiss
Zacian-Crowned. You must really have it in AG format. Its almost the most powerful Pokemon in Gen 8
The suggested set is
Zacian-Crowned @ Rusted Sword
Ability: Intrepid Sword
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Swords Dance
- Close Combat
- Wild Charge
- Behemoth Blade
I hope this team will help you a lot.
Hope I helped.
