after laddering a bit for olt, i'm just gonna point out some of the things i've noticed
HO right now is kind of bullshit and very hard to play around with all the different kinds there are. you can be versing suicide lead rocks lando + dual screens koko + lucha + 3 other setup sweepers or you can be versing veil + suicide lead drill etc etc. basically ho is really good right now. some of the mons i've been seeing a lot on these ho's are suicide lando, alolan ninetales, dual screen koko, hawlucha, mega gyarados, sub cm speed boosting blacephalon, double dance zygarde, sub leech glare serperior and shift gear magearna. what really makes these teams hard to deal with is that a lot of these mons have a really great amount of bulk along with the power and setup capabilities.
some mons im really loving to use are tapu fini, kartana, kyurem b, rocky helmet chomp, and mega mawile, and i've also seen a good amount of usage of rotom-wash and jirachi which i think are also in a pretty good spot right now in the meta.
Tapu Fini:
I think this one is really peaking right now because it is just such a great blanket check to so many things in the meta. when you look at the top mons in the meta, you realize that fini beats almost all of these: lando, non grassium z heatran, clefable, zygarde, ash greninja, toxapex etc. a lot of these mons seem like fini can't beat them, but that's where taunt + nature's madness comes in. this combo of moves allows fini to kind of beat stall by itself as well as allowing it to handle things toxapex celesteela and ferrothorn to an extent. you pretty much need moonblast for ash gren, zygarde etc and if you don't have a defogger it can do that, and if you do have a defogger you can fit scald/hydro/surf to make it a better check to things water types are strong against. all in all this thing is really great right now and definitely is a premier mon imo and i noticed i end up putting this on a lot of my builds.
Kartana:
I've never loved kartana like some others have, but i feel like right now is the best its ever been. i'm really loving banded because its just so strong and can outspeed a lot of things and then just 2hko a lot of resisted mons, and it can knock things like celesteela or tangrowth. band is also really good because leaf blade and smart strike are pretty spammable late game and beast boost gives this thing a ridiculous attack stat and you end up just snowballing teams. scarf is also as great as ever and really helps against those hyper offense teams i mentioned earlier. SD is good, but i feel like if you want to use that you should just use sd bulu or banded kart instead.
Kyurem B:
Kyurem B is really good because although it doesn't have a great overall matchup against HO, with subzero slammer you practically guarantee at least one kill a game and if you can get it in safely, HO teams have no switchins to any of this guy's moves. it is also really good against balance, something else that is super prominent right now in the meta. theres not much different with kyurem i just wanted to post out that it is still really good right now and should not be slept on.
Garchomp:
This seems weird, but i really feel like garchomp is in a great place right now. it's helmet set is really good because it is great at getting up rocks and it is one of the best heatran switchins you can get. i feel like right now when i verse HO teams this is the mon that puts in the most work. helmet + rough skin is great for chipping things like mega gyarados and landos if they u turn on you and stuff like that. dragon tail is also amazing to have for great chip and obviously cause it just phases things like hawlucha kartana gyarados etc that thing they can just set up on you. a lot of people don't really no what to do against this mon when they're using HO and end up just getting their team weakened a bunch by this. (for those wondering this is the set, ev's to outspeed heatran

Mega Mawile:
I've always been a big fan of this pokemon and i think right now it's at the best it's ever been. it kind of hurt me to admit that sd isn't the best set anymore, but it's true. the all out attacker set, although it looks extremely weird, is amazing right now. it doesn't carry sucker punch or play rough but almost no teams can switch into it at all. steel electric ice fire coverage is absolutely ridiculous and i think this is one of the best breakers in the game right now. standard defensive mons like tangrowth, celesteela, landorus, toxapex etc can't afford to switch into this guy because they are risking just dying right away.
Rotom Wash:
While i don't feel like this is great, i do think it is better than a lot of people give it credit for. the ability to just switch into most heatrans, landorus, and greninja a couple times and either cripple them with will o wisp, get momentum or just defog is great. a lot of teams also don't like switching into this thing at all just because it is very hard to find a mon that's fine with taking a hydro volt switch or will o wisp all in one. this does has its flaws and can be easily pressured but the fact that it has iapapa is really great to basically give it a second life and a chance to defog again.
Jirachi:
I think this mon is really, really, amazing right now. the set that i'm using (
http://pokepast.es/872f284c9072e4e6 standard set with bodyslam for para's and enough speed to outspeed heatran and u turn on it) is really good imo. this thing can pretty much almost take a big hit whenever you need it and gain you momentum, set up rocks, or para something. it is an amazing switch in to tapu lele and magearna and can be a nice situational check to things such as kartana and kyurem black. the fact that you can outspeed heatran is great because you can set up rocks as they switch in on you, and instead of having to make a read with a hard switch you can u turn and react to if they switch out or stay in.
