Some changes are necessary so that your team would work better.
Arceus-Ground if you are trying to run it defensive,then EV spread you gave isnt really good.
Most importantly Ice Beam>Special Rend.
Ice beam counters a lot of pokemon like Zygarde,Rayquaza andmost Dragon types and Ground Types.
Arceus-Ground @ Earth Plate
Ability: Multitype
EVs: 252 HP / 240 Def / 16 Spe
Bold Nature
IVs: 0 Atk
- Judgment
- Ice Beam
- Recover
- Refresh
This is a defensive set with this you can make a check to Zacian-Crownd and NDM and the pokemon listed above.
+3 252+ Atk Zacian-Crowned Behemoth Blade vs. 252 HP / 240+ Def Arceus-Ground: 351-414 (79 - 93.2%) -- guaranteed 2HKO
+3 252+ Atk Zacian-Crowned Close Combat vs. 252 HP / 240+ Def Arceus-Ground: 281-331 (63.2 - 74.5%) -- guaranteed 2HKO
Even ater Swrods Dance it requires a 2HKO
0 SpA Earth Plate Arceus-Ground Judgment vs. 4 HP / 0 SpD
Zacian-Crowned: 270-318 (82.8 - 97.5%) -- guaranteed 2HKO
0 SpA Earth Plate Arceus-Ground Judgment vs. 252 HP / 4 SpD Prism
Armor Necrozma-Dusk-Mane: 211-249 (53 - 62.5%) -- guaranteed 2HKO
0 SpA Arceus-Ground Ice Beam vs. 252 HP / 0 SpD Zygarde: 316-376 (75.2
- 89.5%) -- guaranteed 2HKO after Leftovers recovery
Even at 0SpA it Gaurantees 2HKO of every pokemon mentioned above.
Zacian-Crowned is really a hard hitter as you mentioned.But Swrdos Dance would be better over Play Rough.
Zacian-Crowned @ Rusted Sword
Ability: Intrepid Sword
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Wild Charge
- Close Combat
- Swords Dance
- Behemoth Blade
After Swrods Dance it Gaurantees mostly OHKO exept to some like Ground-Ceus.
Defensive NDM has a higher viability rank.It is also a primary Zac check.
Necrozma-Dusk-Mane @ Rocky Helmet
Ability: Prism Armor
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Stealth Rock
- Thunder Wave/ Toxic
- Morning Sun
- Sunsteel Strike
You can fill anything in the second slot and defensive would work better and a hazard setter.
If you want a Ogre let it be Scarfed/Specs
Kyogre @ Choice Scarf
Ability: Drizzle
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunder
- Ice Beam
- Origin Pulse
- Water Spout
Here I choose Scarf for some reason I'll tell.
Scarf can almost outspeed all and Water Spout makes many Sweep.
Yveltal is better as a Dynamax Sweeper.But still if you want to run it a Caly counter sure you can.
But anyways HDB>Leftovers
Yveltal @ Heavy-Duty Boots
Ability: Dark Aura
EVs: 248 HP / 8 Def / 252 SpD
Careful Nature
- Foul Play
- U-turn
- Taunt / Defog
- Roost
You can have Defog to remove Hazard or Taunt can be used to stop Hazards and Baton passers.
Foul play is really good when you use it against Zacian as it calculates the opponents attacking stat.
0- Atk Dark Aura Yveltal Foul Play vs. 0 HP / 0 Def Calyrex-Shadow:
508-604 (148.9 - 177.1%) -- guaranteed OHKO
+1 252+ Atk Dark Aura Yveltal Foul Play vs. 4 HP / 0 Def Zacian-Crowned: 183-216 (56.1 - 66.2%) -- guaranteed 2HKO
So as per the calculations,you can counter Caly and Zac at the same time using this set.
Finally Caly
Calyrex-Shadow @ Life Orb
Ability: As One (Spectrier)
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Astral Barrage
- Psyshock
- Baton Pass
Psychock is a lot better than Psychic and Draining Kiss wont do much damage on the Yveltal.
The reason behind the Scarf of Ogre is Caly!
Youcan just Baton pass to Ogre and Make the greates sweep with Scarf+SpA.

Hope I Helped
