Wow, this is such an incredible tournament run, and I am so happy to be here. I want to talk about something near and dear to my heart now: CorvBlissPert
These mons generate an insane amount of momentum together. Surround them with three strong sweeper/wallbreakers who enjoy switching in for free, and you've got a
stew team going. Lead with an attacker, break things until you get forced out, switch to whichever pivot handles the threat best, and then Teleport/U-turn/Flip Turn to whichever attacker threatens the current mon.
Chansey as always is your catch-all special wall. Very few special attackers can break through it, so when one of your mons is forced out by a special attacker, switch to Chansey, sponge the hit, and then Teleport away and heal with Regenerator. In many battles the only move Chansey will use is Teleport, turning what is normally a momentum-killing mon into a great generator.
Soft-Boiled and Seismic Toss are pretty standard moves so you can recover against more potent attacks and deal some damage back. You have a lot of choices with the last move slot including status, status healing, and secondary hazard setting, but usually it's best to just Teleport away. Sadly Wish+Teleport is an illegal combination.
Blissey is a good alternative here. She can hold Heavy-Duty Boots and is less crippled by Knock Off, but I have found Chansey's better bulk and Corv's excellent Defogging abilities usually mean Chansey is the better pick.
I have changed my mind, I would now recommend Blissey over Chansey. Knock Off is too common right now. Also Heavy-Duty Boots takes more pressure off of Corv to defog, helping its longevity as well by giving it more turns to Roost.
Corv is physical pivot #1 and it's a great one. It checks a wide range of physical attackers boosted by either Intimidate or Dauntless Shield. Even powerful neutral attacks have a hard time breaking through:
-1 252+ Atk Choice Band Barraskewda Liquidation vs. 248 HP / 252+ Def Corviknight in Rain: 153-181 (38.3 - 45.3%) -- guaranteed 3HKO
Intimidate is probably the better ability here, since Corv will normally be switching out immediately, and it allows it to hand off a weakened attacker to Swampert if Corv can't fully check it. However, Dauntless Shield+Body Press gives Corv a surprising amount of offensive presence and should not be discounted. Rocky Helmet is great for punishing physical attackers, but Leftovers can get a small bit of extra recovery (usually not much, but every little bit helps). The zero speed IVs are important for having as slow a U-turn as possible.
Since Corv is the only pivot without Regenerator, and is responsible for Defogging hazards if they are up, it is the easiest one to wear down, so spam Roost liberally. Remember you have a secondary physical pivot if you need to recover and then hard switch. Even without Regenerator, it is an amazing pivot that is hard to wear down.
Corv is weak to Fire and Electric, so another physical pivot that can handle them is required. Enter Swampert! It's amazing typing, access to Flip Turn, and good-enough physical bulk make it a great teammate to Corv.
The set is pretty straight-forward. Flip turn as much as possible to take advantage of Regenerator and build momentum, Stealth Rock if you have a free turn and the other team is weak to it, Earthquake as secondary STAB and Toxic to hurt walls. It is not nearly as physically bulky as Corv, so don't expect it to be, but it can take a hit and switch out.
This core will only ever be as good as the attackers around it. If you don't have dangerous and powerful attackers to take advantage of all the free turns, this team will eventually fold to repeated powerful attacks. They aren't walls, they are pivots, so make sure you have something worth pivoting to and can punish the opponent right away.
The biggest weakness this core has is set-up sweepers that can boost speed. Genesect and Volcarona are the best examples; if they get up a Shift Gear/Quiver Dance they can outspeed your attackers and muscle through your pivots. However, if you're able to keep momentum up, it should be very hard for them to set up. Ideally your attackers will deter set up if they are out, and if they try to switch-in on a pivot you will hopefully be pivoting out, but a well-timed double switch or catching Corv on a Roost can spell trouble. Repeated strong neutral attacks will also eventually wear down this core, but hopefully before that happens your attackers will have already done the same to the other side.
Weavile is also a big threat to this core. It can wear down both the physical pivots, but it will take 2-3 switch ins each to finally knock them out, so make sure at least one of your attackers beats Weavile one-on-one to punish them for bringing Weavile in.
