Hi! I'll be making a few changes to your team based on some of my knowledge and my experiences when I tried using your team. If anyone thinks that the changes I made could be better, feel free to comment on my answer.
changes and commentary will be bold
With that said, on to the changes!
The King (Zacian-Crowned) @ Rusted Sword
Ability: Intrepid Sword
EVs: 252 Atk / 4 Def / 252 Spe
Naive Nature
- Behemoth Blade
- Close Combat
- Play Rough
- Swords Dance
As a steel type, The King already resists psychic types, so crunch won't be necessary. I personally don't think that you necessarily have to change psychic fangs, but I would rather set up a swords dance on the first turn to sweep more effectively. It's up to you if you want to change it or not.
The Jester (Marshadow) @ Life Orb
Ability: Technician
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Spectral Thief
- Shadow Sneak
- Close Combat
- Stone Edge
I already think that The Jesters' moveset is good. I would switch out blaze kick for stone edge instead so that it can hit flying types, which The Jester is weak to. Also, I threw in the life orb for a 1.3x attack boost
The Queen (Kyurem-White) @ Life Orb
Ability: Turboblaze
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Dragon Pulse
- Fusion Flare
- Ice Beam
- Roost
I replaced Volcarona with Kyurem-White to give coverage for fire and ground types. Dragon pulse and Ice beam are STAB, fusion flare is for the steel types and roost is for recovery.
The Guard (Ninetales) @ Heat Rock
Ability: Drought
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Fire Blast
- Energy Ball
- Toxic
I replaced Torkoal with Ninetales for a few reasons. One being that Ninetales is not only useful for setting up harsh sunlight, but also has decent SpA and Spd. Nasty plot is for set up on the first turn. Fire Blast is STAB and Energy Ball is coverage against water and ground. Toxic is for chip damage
The Baron (Venusaur-Gmax) @ Heavy-Duty Boots
Ability: Chlorophyll
Gigantamax: Yes
EVs: 4 HP / 252 SpA / 108 SpD / 144 Spe /
Modest Nature
- Solar Beam
- Weather Ball
- Earth Power
- Sludge Bomb
I changed the EVs because I want The Baron to be somewhat bulky, fast and hard hitting. Chlorophyll will activate and solar beam will be useful once harsh Sunlight is set up by The Guard.
The Swordsman (Corviknight-Gmax) @ Leftovers
Ability: Mirror Armor
EVs: 252 HP / 4 Atk / 252 Def /
Impish Nature
- Brave Bird
- Defog
- Iron Head
- Roost
I replaced Doublade with Corviknight because I think that Corviknight is bulkier by default because of its stats and because of its typing. Flying and Steel is a great type combo because they are weak only to fire and electric, which the rest of your team can handle. Corviknight is also immune to poison and ground type moves. Corviknight gets STAB from Brave Bird and Iron Head. Defog is for getting rid of hazards and roost is for reliable recovery from damage or from the recoil of brave bird.
That's all I have to say.I edited this again because of the criticisms of the first comment (thanks NebbY). I hope this rating helped. Good luck with your battles! I also really like the nicknames you gave your pokemon.
this is the final team.
