*I have been trying to construct my team, and it may have flaws to it since it lacks type coverage on the offense, but I think it's fine on the defense (I hope), this is what I got so far:
Bronzong @ Leftovers
Ability: Heatproof
Nature: Sassy
EVs: (252 HP, 86 Atk, 80 Def, 92 SDef) (IV 0 Spd)
Move 1 - Earthquake
Move 2 - Explosion
Move 3 - Gyro Ball
Move 4 - Stealth Rock
Purpose: Bronzong is my lead and my sort of mix wall, yet I pretty much start with stealth rock ASAP, and I either sweep, switch, or explode to get a free switch if t will deal something to the opponent (do it if a ghost pokemon is not there or a switch to a ghost pokemon occurs). The reason I hav heatproof over levitate, is that many that use bronzong will predict it will have levitate, so with heatproof, I shouldn't be so scared of any fire based moves (unless they got a boost), and be able to set up my SR and sweep (if possible) or switch, I just have to watch out when someone uses earthquake when I switch to bronzong or if spikes have been used.
Problem: I saw that metagross can almost play an exact type of role, with the plus of the ability clear body, better stats, and instead of using gyro ball, it's bullet punch, and I can still get a heatproof like item for metagross with occa berry, but doing so leaves my team half weak to earth, that it still shows with bronzong, but if I don't reveal the ability heatproof, then I would be fine, and I was thinking if meatgross would make a better replacement for bronzong, and if so, then it would be best to replace lucario for scizor, so it won't have a bad type coverage on my team from the defensive side, yet i'm not sure if it's worth replacing.
Tyranitar @ Leftovers
Ability: Sandstorm
Nature: Careful
EVs: (252 HP, 252 SDef, 6 Def)
Move 1- Crunch or Payback
Move 2- Curse
Move 3- Rest
Move 4- Sleep Talk
Purpose: I think making Tyranitar into a special wall or cursetar was much better ( I think) than the more common movesets, since they might have an advantage when used, only problem is his common weakness, & 4x weakness to fighting is the biggest problem when not played on the defensive side, and he is kinda slow to use in battle for offense, so I think with its awesome hp & sdef (thanks to sandstorm), it would give it almost 500 SDef with the ev set up for it, that should make it close to using a blissey (that I hate), only with more weakness and cooler looking, so I just have to boost it with curse a few time so it can also stand up and fight or defend against physical foes, and when I get to hurt, I'll just rest and sleep talk from there, that most likely after a curse boost or 2, will have the survival for most attacks, and makes a great pokemon (if done correctly) to stalling and possible becoming unstoppable, especially if there aren't any pokemon that can use fighting type movs left.
Problem: Its not any big deal, but was deciding if payback is more useful or crunch for a moveset like this, since payback would have more power due to being slow, but crunch has more pp, and was recommended more to use, plus that it ahs the possiblity of lowering their defense, that helps, yet still don't know which is worth more to use.
Gyarados @ Leftovers
Ability: Intimidate
Nature: Adamant
EVs: (156 HP, 108 Atk, 102 Def, 144 Spd)
Move 1 - Dragon Dance
Move 2 - Stone Edge
Move 3 - Taunt
Move 4 - Waterfall
Purpose: It's my bulky Gyarados, I really don't have much to say as the 2 above, but I just simply use dragon dance to prepare sweeping, or use taunt first to stop any of those pokemons that would screw it up, or just to make sure something doesn't go wrong, then simpy sweep away, and if done right, I could just sweep the whole team, sort of similat to tyranitar.
Problem: minor, but is it worth replacing taunt for ice fang and making it more offense as well by changing the Evs to 6 HP, 252 Atk, 252 Spd, that would make it easier for sweeping with the life orb in place, plus I would have an ice move, yet woudn't be bulky anymore plus it would have problems in the sandstorm situation, so I don't know if it's worth it.
Gengar @ Leftovers
Ability: Levitate
Nature: Timid
EVs: (6 HP, 252 SAtk, 252 Spd)
Move 1 - Focus Blast
Move 2 - Hidden Power Fire
Move 3 - Shadow Ball
Move 4 - Substitute
Purpose: Gengar was made like this instead of a pure sweeper, so it can have some way to back up its fragile defense using substitute, then simply sweep without getting hurt, that would save me a lot of trouble if done right, without killing itself.
Problem: Nothing here for gengar, but if you think there should be some changes or there is a problem, just tell me.
Salamence @ Life Orb
Ability: Intimidate
Nature: Naive
EVs: (82 Atk, 176 SAtk, 252 Spd)
Move 1 - Draco Meteor
Move 2 - Fire Blast
Move 3 - Roost
Move 4 - Brick Break or Earthquake
Purpose: Pretty much my mix sweeper of the team, as I would simply sweep through the team, as I have my physical move for those strong against special or they are justs imply weak to it, fire blast for the steel, and draco meteor just for the unexpected, or just to perform a hit & run tactic.
Problem: not much but just to decide if earthquake is better or brick break, as earthquake can do major do heatran the most in common and some others, and brick break can do most on tyranitar, and can help a bit more than earthquake when dealing with blissey.
Lucario @ Life Orb
Ability: Inner Focus
Nature: Adamant
EVs: (6 HP, 252 Atk, 252 Spd)
Move 1 - Close Combat
Move 2 - Crunch
Move 3 - Extremespeed
Move 4 - Swords Dance
Purpose: Simply my Sword Dance sweeper, that I just boost then sweep away, as lucario can do a number of enemies with just 1 boost, but if I get lucky for a second boost, then I can pretty get ready for some good old fashion team sweeping with just lucario
Problem: Nothing wrong that I found of Lucario's moveset, but if there is a need for changing or you see a problem, just tell me.
*These a some things that I was trying to see if it's possible to change, but ATM, I can't seem to figure anything out for it:
Jolteon - I was trying to find a way to switch maybe gengar for it, since they both in offense have a similar use of moves, maybe the difference is baton pass & the HP that is best for them to use, but the problem is that it would leave a bigger gap for earth moves to deal a number on my team, and nothing else does any better at the job for switching
Vaporeon - I thought that switching gyarados for vaporeon much have advantages for my team, such as a healer, and possible a subpasser if I don't it for jolteon (not sure for either), and can still sweep and survive, as gyarados has a similar taste, but can be screwed by electric moves if played wrong or just didn't get to prepare with dragon dance early enough, yet doing so, might have some problems with dealing with some foes if done so.
Skarmory - I was seeing if switching bronzong for skarmory might be a better alternative than metagross, and it might do well at first, plus would let me keep lucario, as my team is fine that way in type covearge from the defensive side, but the thing is that skarmory is more known to dealing with than bronzong, and it could become a problem, yet don't know if it's a good idea to do so, but it would give me a flying type move that would help against fightig types like machamp, and especially heracross, when comparing to bronzong or metagross, I'm still puzzled if it's worth doing.
*If you have a solution for these problems, just tell me, and also tell me wht you think of the team so far.
