So for this part, i will share the teams that had the most success (mainly because if I share everything i build i wld need the entire thread to do so).
gmolt offense :
this team was made for week 6, to face against Kate. I knew offensive stuff like this would win and I was right to believe so. Protect on dia is something I was always fond of, helps a lot winning mindgames against the likes of gren/kart/lando as absorbing lop's fake out, which can be usefull to stay out of the close combat range from full. Rest is p straightforward, gmolt is ev'd to outspeed pert under the rain after an agility while maximising its bulk and damage output.
I like this team cuz you really need to play offensive, you take advantage v early on by doubling and pressuring to choke your opponent out thanks to the fact that 5 of your 6 mons is a potential wincond that can make progress.

weav darkinium lele av offense :
I always see a lot of people talking about how groundium weavile is good but trust me it's not, it's a fake set. Real set is Darkinium, although you drop knock you ensure a KO on a lot of things weavile wants a KO on, including Skarm and Corv after rocks, which is really good. AV on lele is a really good thing to use, improving its bulk and allowing him to stay and weaken stuff like tran or even KOing ash-gren. Toxic is an option I personnaly like on Kart, as it's a good way to weaken zapdos without risking a paralysis if you can't manage to maintain fini's terrain up. It can be totally switched for smart strike, but i'm always paranoid on demon setters, so it's a good option nonetheless. It's a way more aggressive and volatile team than the first one, however, it's probably the only one i wldn't recommend as a sample, because you need a very good understanding of how the tier works and how to deal w certains threats.

pads melme + speed tana offense :
It's a very similar team compared to the one i posted upper, and also a completely different team. Main goal here is to use melmetal to twave stuff like corv/skarm/pex to abuse them later w either kart or weavile. I think +speed kart is really underated as a wincond, it does an insane job at 6-0ing teams unprepared, especially in this offensive zapdos era. It terms of how to play it, it's similar to the first one, you want to be aggressive to pressure and then win by setup either weavile or tana.

mmedicham paraspam bulky offense :
Since I only posted fast paced offensive teams, I think it's time for something a bit more bulkier, although it's an offense. So originally this was made for devin for week 2 against Lily, although the team featured a dnite over weavile at the time. The concept is simple, you make everything slower than medi and you trap/remove everything that resist its stab duo so that it can freely spam hjk/zen (assuming you don't miss). I like having bullet punch here as an option to deal w diancie, as this mon is a bitch for such bulky offense teams that relies on ferrothorn as their steel. Clef's spread was made to outspeed 100 bs full invested w a + speed nature AFTER the paralysis, so that you can heal on them. Team relies a lot on paralysing stuff, including volcarona/rem (you can catch both of them w ferro/rotom). It has p good MUs overall, outside of stall, which on a scale from really hard to win to impossible is at forfeiting is your best shot. To play this, you need to be aggressive in your passiveness, if that make sense, like going for reads w twave, you want to punish as much stuff as you can w paralysis.

Kyulop + melme offense :
So this was originally something I made for daruma, against Stareal during NDWC, and made a refine for the tiebreak against Bea, although the team didnt have the best showing during that game, considering how bad it went for both side in terms of rng influence. Team itself isn't that hard to understand, it's mainly just Kyu-Lop core combined w a fast paced offensive core team. I think icium rem is hella busted, mon doesn't have proper switch in and you always have reward by just clicking mindlessly w it. Punny is double prio for patching certain MUs, including HO, and I don't see u-turn being good in that structure here. I like how vic patch a lot of things here simply thanks to its typing, it's litteraly the defensive glue of the team for a lot of mons. Heatran can be a bit annoying if you don't know how to handle it properly (meaning you need to have your terrain up and rocks out), it's a bit of a technical build in a way cuz you really need to know how to handle and dance w a terrain, especially there since 1 of your mons have toxic and want to toxic stuffs. You need to play this aggressively, as most of the stuff I leaked anyway, what's the good thing to do is to make sure Kyurem enters as much as it can on the field and then you click until something dies. Some sequences can be tricky, esp w how you use your Z move, but after you make a huge break it should be more than fine to conclude.
