Now that the UUBL tours have ended, I think it's time for me to share my thoughts on the VR. Tho I didn't win anything, I'm very happy with what I built for
THE_CHUNGLER & how I could help them in their run. They played incredibly well & my teams were just a mean to showcase it.
Anyway :
Raikou is the best mon in the tier, no debate, I hate it in this tier, pls ban it,...
More seriously, this mon is truly broken. There is no true counter to Raikou & you can be sure it will be troublesome to your team. Tho I find it a bit easier to handle the more I play, but it's also cause I play 1 or 2 "hard" kou check in every team (cause you're forced to), but yeah this kinda sucks that it forces team slots so hard.
Kou's strongest sets truly are the ones that are not Tbolt/Sub/CM/Random HP, the strongest truly are Roar & Toxic variant that can take advantage of how bad Spinners are in this tier or that can force Chansey to not use Toss, which means almost guaranteed crit (which means free W). Also if you win the roar roll on oppo Kou you win the game.
EDIT : Roar is the best Kou coverage, because if you face Kou wall, you can roar it out. Then you have 80% to 100% chance to have smth that doesn't check you (depending on the team). Which means you either get a kill or force out the Kou check, either damaging it on the switch or boosting. You make progress anyway, & you'll never get roared out cause you're faster than everything. They can try to switch out so they can get the better odds to get their check in, but it's giving a 50/50 to Raikou (don't do that) & you lose momentum for nothing + spikes probably up + ff you face Kou, just bring Chansey + Steelix/Registeel.
It's not as versatile as Dnite in the builder, but it's way stronger than anything else in the tier with only 4ish different 4th move variants. (also easy to build around)
Everybody loves Dnite. Easy to build around, fun to build & tweak to your likings, good af & most importantly not so hard to check (4x weak to ice), which makes it way healthier than the dog above.
Of course DDnite is very strong & can easily get out of hands if you don't do anything quickly. Flying + Ground coverage is insane & it's also helped a lot by the access to Ice Beam just to be sure Donphan can never be a Dnite check (and top tier).
Dnite also gets access to cool secondary coverage in case you don't want to run Ddance & prefer more balanced set like me. Fpunch is incredible into Regice, Oma & other stuff & Thunder is also very good to hit bulky waters that loves coming in.
The mon also gets utility like Heal Bell, Twave, Toxic, Roar, Haze,... if you need. Heal bell comes in the more often & it's rly good if you wanna run Wish Chansey for example.
Anyway love that guy, my Anti Dnite Dnite is my fav set.
Registeel versatility & incredible defensive potential is what makes it so good. You can lead with it, with things like twave, boom, counter, eq,...
You can curse sweep (tho it is not so good now). You can run some madman defensive set with Amnesia to be able to win vs Kou & Zam. Some good Rest heal can fit very well with heal Bell support. You can do what you want with it, tho its strength mostly comes from how it can check Kou thx to Toss/Eq. Love it.

Medi does too much dmg, only true check is weezing. Para flinch it & you win. Thankfully Dnite is in most teams to tank a hit or two & OHKO it.
This is my fav lead in this tier, good enough speed to OHKO most spikers & Fake Out can chip things or disable Slaking, while checking for lefties T1. Access to Sball makes it able to ruin Slowbro's life once it clicks rest.
TLDR dmg too big, can't check it indefinitely.
This is the mon who makes so many things thrash (hello crobat). Wisp / haze makes it a very good Curse/slow SD disabler. Typing & stats helps to check most physical threats (mostly Fighting types). You can custom it with Hp Ice if you need help vs Dnite or if you fear Sub Rhydon.
Just extremely solid.
I'm the biggest Chansey spammer. Heal bell is very good. Also it's just the most consistent Kou check, until you get crit'd (at least 1/2games). Also checks so much things. Twave is incredible, you can run Toxic if you hate Donphan & Rhydon. If regice doesn't run boom, it's free. Heal Bell is ultra strong, you can also run Wish instead if you have another Heal Bell & need to give some support to Blastoise or smth.
Love that bro. CM rest. This is good cause it checks Weezing & other bulky waters. Also you don't get OHKO'd by anything. Only problems are free Kou entry points, Chansey & Psych Up Regice. You can run Twave instead of Surf if you want to para spam, Fpunch can help vs Chansey/Regice Switch ins, but it's not that good.
Just play CM Bro everywhere, it's fun & good, I promise.
Dnite Check, Dodrio/Tauros check, Best Spiker. Crit immune is cool. Cause of this thing my boy Tauros is not so good. Pairs perfectly with things like Weezing & Chansey.
Kinda Kou check. Checks Dnites unless it's Fpunch (they should play it). Checks the water mons thx to Tbolt. You can rest for Status heal. Boom is cool. You can also play Psych Up if you hate Slowbro & Kou & wants to lose to chansey. I just prefer running Chansey/Registeel, but it's good.
Thick fat is nice for Houndoom & Regice. Very cool lead thx to hp & movepool. Knock off is a free click that makes Weezing/Slowbro easier to handle. EQ for Kou. You can also get more utility with Whirlwhind, ResTalk, Counter,...
Play it on stall, on balanced, even on offense. It will always do smth. Tho I prefer Medicham as a fighting type cause unchecked, raw, faster dmg is often better.
Bulky water that checks Dnite & Wish pass. Free Slowbro set up. Toxic forces rest on stuff tho.
Very good Offensive spiker. Dbond can trade with Slowbro that's forced to come in. Boom can also trade with stuff. Twave is incredible support for a spiker lead, mostly on offense. Doesn't get OHKO'd by Medi, & it's faster, also poison point scare them from clicking Fake Out. You can also play CB.
CM + Synchronize. You can Encore sometimes.

Sub SD is so good lmao. Toss immuned, faster than most defensive mons, beats non Hp Ice Weezing. Gets some easy wins on some MU. Extremely good to switch into Chansey (unless they run Toxic)Also CB can be good.
Steelix stocks are rising thx to 90% of HP on Kou being Ice. Nobody runs Water. OK Normal Check. Roar abuser. Forces out set up sweepers.
Tentacruel is the best Spinner (which means how bad spinners are) It's the best cause it's not fucked vs popular Spikers. Non water weak Spiker is so important & having a Toxic immunity helps so much. Also Speed tier. It comes into Houdoom thx to great SpDef. Can get support moves like Toxic, Haze, Screens,...
Also you can try some SD sets.
SD + Guts, easy switch in on defensive stuff & can do some cool sweeps thx to it's bulk. Sometimes it surprises Kou & Dnte & take some good kills with EQ/Return. Easy holes in teams, like coming into Toxic Chansey. Best Normal attacker.
Blastoise. I think it's currently the 2nd best Spinner cause of things stated above for Tenta : It doesn't suck vs the 2 main Spikers.
Water resist is so important & it's also an actual soft Dnite check thx to Bulk & Ice beam.
Access to Refresh makes it easily viable vs defensive mons that rely too much on status. EQ being available is so good for Kou switch ins & to help threaten Qwil & Tenta who think they are free. You can also run Foresight shenanigans for funny spin on Ghosts.
Unfortunately it heavily relies on Wish support to work at it's full potential, but some teams can run it without, but needs to play very good/careful.

Gonna End with Hitmontop, probably the strangest choice of the list, but I think it's coherent.Hitmontop Niche is sooooo good. It's a Spinner with intimidate & a PRIORITY MOVE. Priority moves are ultra rare in this tier. The most common one is Medi's Fake Out, but it's not so good cause it's always banded. STAB Mach Punch is very important, so you can apply pressure on around 1/4 hp fast threats. Also intim makes it a good lead. It puts you out of Kill Range from things like Medi, that you can kill instead with your CB Hp Ghost. Also you get the very important EQ, that will OHKO Kou lead.
Hitmontop is the role compression of your lead Fighting type with Spin, but that also wins a lot of very important lead MU for some reason.
That's it for now, I think the rest is pretty usual. If you need me to explain some specific postion of mons, or what's my opinion on some stuff, don't hesitate. I'll surely drop some of my fav teams here at some point. Some of them can prob be Sample candidate.
I love Entei, it's Healthy Kou that beats Toss.
