This Team got me to the 2nd on the ladder, but has now dropped to 5th, partly because i haven't played in a bit. Hopefully you can help with that. The team has a few surprises and is stall-oriented.
Mesprit(?)@Leftovers
Nature:Calm
Ability:Levitate
Ev's:252HP/40Def/216SpD
-Stealth Rock
-Psychic
-Thunderbolt
-U-turn
Mesprit leads off the team and makes sure to get SR up ASAP. Since this team lacks raw offense the extra damage helps a ton. Psychic is for STAB and hits fighters/poisons hard. Thunderbolt helps against waters and flyers like Staraptor. U-turn is a scouting move after setting up rocks and predicting switches. It also annoys subseed Aboma leads. The ev's were turned for more defense on the special side, the only physical attacks i'll switch Mesprit in on is Fighting moves, which it resists, and Earthquake, so having more special defense to soak up those Overheats, Eruptions, and Surfs comes in handy.
Milotic(F)@Leftovers
Nature:Bold
Ablity:Marvel Scale
Ev's:252HP/252Def/4SpD
-Surf
-Ice Beam
-Recover
-Haze
Milotic is a great Bulky water and a real bitch to take down. It provides great water, ice, and fire resists to the team. Surf for STAB and Ice Beam for coverage. Recover to heal up while Haze is a great new addition which stops enemies like NP Slowking, DDgator, and CMtomb. I would've liked to fit HP electric somewhere, but I don't think Milotic really needs it in nUU.
Spiritomb(M)@Leftovers
Nature:Bold
Ability:Pressure
Ev's:252HP/252Def/4SpD
-Rest
-Sleep Talk
-Calm Mind
-Dark Pulse
Crotomb has proven to be a great spin blocker and one of the biggest threats in nUU. It's solid defenses allow it to come in, set-up, and then heal off the damage and sweep. Unprepared teams are in for a nasty surprise. A fighting and psychic immunity is always helpful.
Roserade(F)@Leftovers
Nature:Calm
Ability:Natural Cure
Ev's:252HP/252SpD/4Spe
-Toxic Spikes
-Leech Seed
-Substitute
-Sludge Bomb
This Roserade has proven to be extremely effective and a surprise for many opponents. Many are surprised when there Ludicolo's LO Ice Beam only manages ~55%. What it does best, though, is setting up TS. With 2 layers the stalling can begin. Leech Seed + Sub is an annoying combo that allows Roserade to stall out many enemies. Even with no investment, a STAB sludge bomb hurts many enemies, particular those who resist leech seed.
Claydol(?)@Leftovers
Nature:Impish
Ability:Levitate
Ev's:252HP/252Def/4SpD
-Earthquake
-Stone Edge
-Rapid Spin
-Safeguard/Toxic
Claydol was a poke I was a bit iffy about, but it's proven quite useful. It has great defenses to soak up Fighting and Rock attacks, and hits hard with half a STAB on EdgeQuake. I chose physical attacks because it hits pokes like Raikou and Mismagius harder. Rapid Spin is always useful, and Safeguard has been helpful against walls that try and toxic you, and eespecially moves like Yawn from Uxie. I've considered Toxic to help wear down anti-spinners like non-rest Spiritomb, Dusclops, and Mismagius, but i'm not sure about that yet.
Glaceon(M)@Leftovers
Nature:Calm
Ability:Snow Cloak
Ev's:252HP/40Def/216SpD
-Wish
-Protect
-Roar
-Ice Beam
Glaceon is the hidden star of this team, and this set works incredibly well. Glaceon forces tons of switches because specs and scarf variants are always expected, so phazing through they're team and piling on the damage is easy. Wish for team support and Protect to scout and reliably have Wish heal Glaceon, and is very annoying when paired with TS. Even without any investment, STAB Ice Beam stings. This Glaceon has lived through a Blazikens Overheat, don't ask me how, it just did. O-o
Threats;
Staraptor-No Reliable switch-in, but luckily it dies to SR as it always tries to U-turn and Brave Bird.
Clefable-Only the encore variant, it can get annoying.
Sceptile-SD variants. If Glaceon is full health it can survive a Leaf Blade and KO back, but if not then i'm kinda screwed, and i'm screwed anyway if it carries Rock Slide.
Those are the only ones I can think of right now, thanks for looking.
