I made a very offensive team, so I thought, could it work the other way around? Turns out it can. I even came up with UU's version of OU's SkarmBliss combo. This is a very defensive team built to stall, and stall it will.
Bold @ Lum Berry
252 HP / 200 Def / 12 SpD / 44 Spe
Ability: Poison Point
This is a very good lead. Almost none of the UU leads can 1 or 2HKO it so it gets chance enough to set up Toxic Spikes. Ground/Ice provides perfect coverage in the UU metagame and they're powerful moves anyway. Lum Berry is for (faster) sleep inducing leads, which could counter this set.
Relaxed @ Leftovers
252 HP / 4 SpA / 252 / SpD
Ability: Shell Armor
Standard Cloyster set, but very good in a stall team. It's wickedly high defense is very stallish and Rapid Spin can clear my side of entry hazards which some are weak for (including himself/herself). This one also has Toxic Spikes, because there will probably be a poison type or an opposing Rapid Spin-user. This one is switched in late-game usually.
Bold @ Leftovers
284 HP / 252 SpD / 8 Spe
Hidden Power [Grass]
This one is very bulky. I maximized its Sp. Defense to mimic the infamous SkarmBliss combo from UU. This is part one of my version of SkarmBliss in UU. With three attacking moves, it looks kind of offensive, it is a bit too but I don't want to be bait for Taunt-users so this one is a bit more offensive. You know what they say, the best offense is defense . Anyways, moves provide very good coverage and Recover is a solid recovery-move which can stall out a lot of Pokemon.
Impish @ Leftovers
212 HP / 252 Def / 44 Spe
This one is the other part of my version of OU's SkarmBliss combo. I call it the 'TorTic combo' . Combined they have no weakness and very good coverage and stall-capabilities. SubSeed combined with solid defenses and free switches between two Pokemon is deadly for every team, the difference with this is that their death will be slow and painfull.
Impish @ Choice Scarf
252 HP / 104 Def / 152 Spe
A ScarfTrick set. It's very good. I can lock down a Pokemon if I want when I want without them expecting it from an Uxie. Stealth Rock can't miss in a stall team with forced switches and Knock Off can bug the opponent even more.
Calm @ Leftovers
252 HP / 4 SpA / 252 SpD
This one takes the place of SubRoost Moltres. Flareon has another stall-technique, Wish and Protect. A bit like Chansey and Blissey, only this one has an immunity to Fire. Stall out with Toxic and Lava Plume with a fairly decent burn-rate and as STAB-attack.
I'm thinking about putting Spiritomb on the team, But I have no idea which one can best be swapped for this set:
Bold @ Leftovers
Hidden Power [Fighting]
the moves give perfect coverage and Rest and Sleep Talk allow very good stall and attacking at the same time. I have no idea though where to put in on the team.
I hope you like it. Please rate and fix where possible.
