I could really use help perfecting this team and am really close to finishing. I am having a tournament with some people in which all legends are banned, but Salamence and Garchomp are okay, that is why I have a Salamence and not something inferior like dragonite.
Swampert @ Leftovers
Swampert is my reliable lead pokemon, and Swampert counters most leads. It sets up stealth rock, and can come back later as a bulky wall. It is a great counter for any fire/electric/rock attacks, and is a reliable way to defeat Tyranitar. Earthquake gets STAB and is super effective against many OU pokemon like Infernape, or Metagross. Ice beam eliminates dragons, gliscor, and several other pokemon. Surf is a water STAB move that can provide large damage to physical walls. Swampert's resistance to fire benefits both Breloom and Metagross who can draw in fire attacks.
Salamence @ Leftovers
Although Uber Salamence is allowed in the tournament. Leftovers provide Salamence extra health and allows it to sweep longer. The Nature and EVs are for maximum damage. Dragon claw is a great physical STAB move, and is resisted only by steel types. Earthquake is one of the best moves, and works well against many OU pokemon. Salamence has a great resistance to grass types, and can switch in from Swampert. Fire Blast murders both grass types who can kill Swampert and Skarmory who would wall Salamence. Salamence's ground immunity works well with Metagross's weakness. Hasty gives it more bulk with intimidate.
Metagross @ leftovers
Ability: Clear Body
Metagross is a very defensive pokemon, and can easily set up an agility. This doubles his speed, and from there sweep. Meteor Mash is a great stab move, that can raise your attack, and provide lots of damage. Thunder Punch can kill Gyrados who may try to set up on Swampert. Earthquake is obvious. Metagross can take an Ice Beam aimed at Salamence or Breloom easily, and sweep from there. It can also take grass attacks aimed at swampert, or flying attacks aimed at Breloom.
Gengar @ Life Orb
Evs: 252 Spatt/252 Spe/4 Hp
Pure special sweeper, and provides levitate support. Life orb increases damage, and Timid Nature gives Gengar a ridiculous 350 speed. All of its moves provide great coverage, and its immunity to fighting/ground attacks allows it to switch in easily.
Breloom @ Poison Orb
Ability: Poison Heal
Breloom is a GOD. This is my last resort and Spore cripples enemy pokemon. Seed Bomb kills both ground and water pokemon. Focus Punch deals huge damage, and is super effective to several types. Substitute provides a wall that can allow it to spore a pokemon if it wakes up, and from fast pokemon who switch in. Its typing provides great team support, but its easy to figure out, and there is no reason to list them all out.
Umbreon @ leftovers
Umbreon provides the team utilities like wish. Payback prevents it from being taunt bait, and taunt is rather self explanatory.
This team is undefeated 11-0 but I would like some feedback especially on smeargle. So far this team has done very well and actually works better than it sounds in writing. I can switch any pokemon out for another pokemon, but only if they absolutely have to. I have all of these pokemon (excluding Smeargle) with Max IV's, but Gengar has 30 in Speed for HP Ice. This is not an OU battle, but it is competitive and Salamence is allowed, and there are no sleep restrictions. Sorry about the gen. 5 pictures, but they looked cool, but this is a Gen. 4 team. Thanks to any help
