Oh yeah, this is actually coming from a total noob shit, so this team may be weak to a list of things that can come up in games. But anyway, here it goes:
Omastar @ Leftovers
Ability: Shell Armor
Nature: Bold
EVs: 248 HP / 252 Def / 8 SpD
Moves:
~ Stealth Rock
~ Spikes
~ Surf
~ Ice Beam
This is my new lead. With access to SR and Spikes, good special attack stat and respectable physical bulk, which is the theme of my team, it gained my trust. Also, it switches into water types much easier than Steelix (lol).
Moltres @ Leftovers
Ability: Pressure
Nature: Timid
EVs: 252 SpAtk / 252 Speed / 4 HP
Moves:
~ Air Slash
~ Fire Blast
~ Roost
~ Hidden Power Grass
The reason that I use Lefties over LO is because of entry hazards and that infamous theme that my team has. LO turned too many 2HKOs into OHKOs, but so do stacked entry hazards. This means, I no longer need to have a LO recoiling me down. Moltres can switch into grass anti-leads such as venusaur and torterra with double grass resistance so that they won't scare my omastar away. By switching into a stab seed bomb or leaf storm, I can guarantee you that Moltres will have his HP reduced more than lefties can recover. But in return, you can ohko them if they don't switch (if they overpredict and think you'll instapredict a switch and switch back to omastar yourself) or switch back to omastar while being against a possible rhyperior and have an opportunity to ohko or set up. Also, moltres is among the best sweepers with entry hazard and spin support, both of which are in my team.
Altaria @ Leftovers
Ability: Natural Cure
Nature: Adamant
EVs: 252 HP / 16 Atk / 176 SpD / 64 Spe
Moves:
~ Dragon Dance
~ Dragon Claw
~ Roost
~ Heal Bell/Safeguard
Set looks self explanatory. Protect team from status effects, stay on the field with roost and lefties support on yourself, set up and smash through things if necessary. But I felt a little bit undecisive on whether i should use heal bell or safeguard. Both have advantages and disadvantages.
Hitmontop @ Leftovers
Ability: Intimidate
Nature: Careful
EVs: 252 HP / 192 Def / 56 SpDef / 28 Atk
Moves:
~ Rapid Spin
~ Foresight
~ Close Combat
~ Rest
Oh, right now I'm pretty much decided on heal bell over safeguard as heal bell can cure rest. Other than that, it's the standard rapid spin hitmontop with some modified EV distribution and rest over sucker punch&stone edge for survivability and close combat for being stab physical if I see a clefable or chansey shitting around.
Venusaur @ Leftovers
Ability: Overgrow
Nature: Timid
EVs: 4 Def / 252 Spe / 192 SpAtk / 60 HP
Moves:
~ Giga Drain
~ Synthesis/Leech Seed/Grass Knot
~ Sludge Bomb
~ Sleep Powder
You can say that I count on entry hazards too much and thus give up attacking power so willingly. I do. Thing is that with Seed/Synthesis and Giga Drain, Venusaur probably won't lose HPs anytime soon (unless my dog plays instead of me and stays in against a moltres or articuno). Other than that, it's your standard special attacker Venusaur with slightly modified EVs and Giga Drain over Leaf Storm (I don't want my special attack to drop by 2 stages when I run on a special set) and possibility of Leech Seed or Grass Knot to replace Synthesis (depends on how much I count on Giga Drain and Lefties). Basically, 2HKOs may turn into 22HKOs and 3HKOs can turn into 333HKOs. Applies for both sides ofc.
Drapion @ Leftovers
Ability: Sniper
Nature: Jolly
EVs: 32 HP / 4 Def / 220 Atk / 252 Spe
Moves:
~ Swords Dance
~ Crunch
~ Earthquake
~ Aqua Tail
And my last lefties carrier... Uh, I mean Pokemon, is Drapion. Choice was not that difficult and set is self explanatory. I'm counting on entry hazards and I removed 32 Atk EVs and Life Orb for 32 HP EVs and Lefties. This guy may happen to be my physical sweeper. That I've been somewhat lacking due to Altaria not filling the role quite well and one not being enough. In terms of lefties sweeping, Rhyperior is still better with better physical bulk, especially special tanks like venusaur and moltres being in the building, but I still chose Drapion over him. Reason is, even though Rhyperior has a better general bulk and having a perfect switch-in partner like venusaur, he's still 4x weak to both water and grass. Grass is something that I can take care of with Altaria and Moltres being 2x and 4x resistant respectively, but I want every single pokemon in my team to be good enough to fill the role. Rhyperior just doesn't get the job done without help. I think that's the reason for him to be in UU.
First Changes:
1- Steelix: Has been changed with Omastar. He has more weaknesses and less advantages compared to him. He may be stronger than Omastar against
2- Rhyperior: Has been changed with Drapion so that I won't be swept by a modest specs alakazam. Alakazam outspeeds all of my team with his base 120. He has a good type coverage along with much better speed compared to rhyperior. Also, he's just as bulky.
3- Nidoking: Has been changed with Venusaur. His type coverage doesn't help with many things. I've thought about him the longest because as a physical sweeper, he's also immune to toxic stall and he's as fast as him. But, even with stacked entry hazards, he can't sweep with lefties and life orb will eventually decay him down.
4- Xatu: My U-wisher, which is replaced by Altaria. You may say that Xatu can absorb status just as well if not better and he can always wish-switch and help my team with heals. But, all of these remove any room for lefties sweeping behind spin support.
My experiences so far:
1- I think I'm 2-2 with this team with both loses being against toxic stallers (lol). But I don't think any experienced person will lose to a toxic staller with this team. I didn't realize that I'm playing against a toxic staller, I should have protected Altaria and Drapion but I played recklessly and lost both early. Other than that, I swept a toxic staller with my defensive hitmontop and another toxic staller with Altaria that set up on 3 Dragon Dance.
2- GigaSeed Venusaur rolls. I could easily stay on the field against neutral opponents and swept things that are weak to grass.
