Don't need the ties since meta beats all the other base 110s as is
To be fair it is probably a better idea to withdraw the EVs from Attack since its literally only three points and three points of Speed lost is much more harmful than three points of Attack.
Well this more or less looks like "weak to Kyu-B" the team, given Earth Power does a chunk to both Volcanion and Metagross with everything else getting blown back by Ice Beam. While things on the team certainly can hit it hard, you do need to factor in the fact that Kyurem-B could have support in things like Togekiss, Amoonguss or Jirachi, which seems like a pretty scary prospect in theory. Rock Slide also is a fair bit problematic given Metagross being the only resist, though with Intimidate support I would deem this a lesser issue, but still one to consider when opting for a choice of which pokemon can round out the team. I'd say a Fighting-type would round off the team well, given we have all of the weaknesses of the average Fighting-type covered well (no Flying-type weak mons, a Psychic-type immunity, and 2 solid Fairy-type resists).
There are admittedly a lot of options that could fit the bill, but here's the one I choose:
Conkeldurr @ Assault Vest
Ability: Guts
EVs: 232 HP / 152 Atk / 24 Def / 100 SpD
Adamant Nature
- Drain Punch
- Ice Punch
- Knock Off
- Mach Punch
The spread here is a meta-updated variant of one made by myself and Laga back in the first XY SPL iirc, the original idea was to beat LO Latios 1 on 1 which still holds true as a LO Psyshock or Psychic cannot OHKO the set and Knock Off will always KO Latios after one round of LO recoil (and Knock Off + Mach KOes from full). The significant difference is that a Modest Choice Specs spread Hyper Voice from Sylveon will not OHKO, given Sylveon (and I guess Gardevoir-Mega tho since it has no item slot it doesn't hit as hard) has become a lot more common since then. Drain Punch + Mach Punch should KO any Kyurem-B set other than one with like max HP investment, which still has a very high chance of going down. In terms of what we can tank relative to Kyurem-Black:
252+ SpA Life Orb Teravolt Kyurem-B Draco Meteor vs. 232 HP / 100 SpD Assault Vest Conkeldurr: 238-281 (58.1 - 68.7%) -- guaranteed 2HKO
252+ SpA Life Orb Teravolt Kyurem-B Ice Beam vs. 232 HP / 100 SpD Assault Vest Conkeldurr: 165-195 (40.3 - 47.6%) -- guaranteed 3HKO
252+ Atk Choice Band Teravolt Kyurem-B Dragon Claw vs. 232 HP / 24 Def Conkeldurr: 268-316 (65.5 - 77.2%) -- guaranteed 2HKO
While Ice Beam into Draco from a full special LO set surpasses 100% damage, note that given Drain Punch recovery it won't actually go down. Overall, Conkeldurr helps to some extent versus Trick Room, checks Kyurem-B solidly, can beat a Latios expecting a KO, and provides a nice Rock resist. While Latios could still be a bit of a problem for the team with Conkeldurr, remedying that would be fine simply by giving Hydreigon Tailwind for more speed control (given we don't need Earth Power that badly with all the ways to take out Heatran), giving Lando-T Knock Off, and other small changes to gain that edge vs Latios. The matchup vs Latios seems doable enough to me without changes as well, given that Latios gets hit hard by Metagross-Mega to begin with and U-turn on Lando-T does quite a lot.
Guts is imo the ability to go with given if Conk were to get burned with another ability, Kyurem-Black would become a big issue once again and Iron Fist is not necessary to get the damage output we need.
-edit-
sorry for original triple quote, very confused as to how that happened
