First, congrats on your success with this team, which helped you to reach 1882! Lycanroc HO is a surprisingly good form of HO in the current Gen 8 Anything Goes meta, which is notoriously good at shutting down other HOs and does good against other play-styles with overall consistent performance.
However, I think your team is a bit different from what the usual Lycan HO carries. Lycanroc is something that generally gets well paired with Cloyster, which is a must-have on this team. It provides Rapid Spin support, decent set-up sweeper with Shell Smash, etc. etc. however, the most important role is played by it easily beating Excadrill, which is something Lycanroc easily hates. Ditto is a niche pick, and I don't justify fitting Ditto in place of Cloyster. Hence, this would be the first change.
- Ditto --> Cloyster
Cloyster @ Focus Sash
Ability: Skill Link
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Shell Smash
- Rapid Spin
- Icicle Spear
- Rock Blast
This is a pretty standard set, I guess. Take a note that this should never come to Necrozma Dusk Mane. It's mainly for Excadrill—you're gonna use Lycanroc to lead against it naturally.
The largest issue with this team is that you're having 4 special attackers. Like, why? Is this because you love getting bullied by Chansey and sisters? Here's what comes: Physical Yveltal!! While it's a weird choice, you absolutely need it because of the Eternatus and Kyurem-W MU—they can more like freely switch-in to everything outside of Calyrex-S, which invites SpD Yveltal that sets up on Special Attacker Yveltal as well. The sweet solution is to run Physical Yveltal, to surprise them for fun. Here's the set:
- Special Yveltal --> Physical Yveltal
Yveltal @ Life Orb
Ability: Dark Aura
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Knock Off
- Dual Wingbeat
- Sucker Punch
- Roost
It's able to deal chunk to Eternatus, Kyurem-W, Yveltal, etc. all of whom are annoying for this team. Some calculations prove this:
252+ Atk Life Orb Dark Aura Yveltal Max Darkness vs. 252 HP / 0 Def Eternatus: 394-464 (81.4 - 95.8%) -- 56.3% chance to OHKO after Stealth Rock
252+ Atk Life Orb Yveltal Max Airstream vs. 252 HP / 4 Def Yveltal: 317-374 (69.5 - 82%) -- guaranteed 2HKO
252+ Atk Life Orb Dark Aura Yveltal Max Darkness vs. 0 HP / 0 Def Kyurem-White: 411-485 (105.1 - 124%) -- guaranteed OHKO
252+ Atk Life Orb Dark Aura Yveltal Max Darkness vs. 248 HP / 208+ Def Ho-Oh: 302-356 (72.7 - 85.7%) -- guaranteed 2HKO
- LO Calyrex-S --> Focus Sash BP
Calyrex-Shadow @ Focus Sash
Ability: As One (Spectrier)
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Astral Barrage
- Psyshock
- Nasty Plot
- Baton Pass
Honestly, you don't always need the raw power. You have Xerneas, Yveltal, Kyogre, etc. already who are big attackers. So, using Baton Pass seems more fun. Also since you already have Yveltal that relies on Dynamax, having another Dynamaxer in form of Caly-S isn't that much beneficial. It's also your priority backup since a Ditto that copies into one of your teammates can pretty much easily reverse sweep.
- Xerneas or Kyogre --> Necrozma Dusk Mane
Necrozma-Dusk-Mane @ Life Orb
Ability: Prism Armor
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Dance
- Sunsteel Strike
- Knock Off
- Stone Edge
This is an absolute need. If you were to ever forgo this on a team, you're jeopardizing your match-up against the almighty Sword Dog that rules over Anything Goes. Aside from that, a strong physical attacker is much requirement of every good team. Pair it alongside Physical Yveltal, and nothing can stop you apart from Zygarde. Knock Off is a weird choice, but it allows you to OHKO Lunala after one Dragon Dance as Max Darkness at full HP straight through Shadow Shield!!
+1 252+ Atk Life Orb Necrozma-Dusk-Mane Max Darkness vs. 252 HP / 252+ Def Shadow Shield Lunala: 499-590 (104.3 - 123.4%) -- guaranteed OHKO
+1 252+ Atk Life Orb Necrozma-Dusk-Mane Max Steelspike vs. 252 HP / 208+ Def Zygarde: 341-402 (81.1 - 95.7%) -- 12.5% chance to OHKO after Stealth Rock
+1 252+ Atk Life Orb Necrozma-Dusk-Mane Max Darkness vs. 252 HP / 252+ Def Prism Armor Necrozma-Dusk-Mane: 294-347 (73.8 - 87.1%) -- guaranteed 2HKO
Xerneas
It's good, but you can optimize the EV spread much better. Modest Nature is absolutely better than Timid in most cases, and I suggest changing the EVs to 44 HP / 252+ SpA / 212 Spe. 44 HP means you're having 101 HP Substitutes, meaning Chansey/Blissey requires 2 Seismic Toss to break one Sub, which is overall annoying for it.
Final Team
Hope this helps :)
