Oh, the way that gravity pulls on you and me (An Offensive OU RMT)

[bonk]

Oh, the way that gravity pulls on you and me​

​

My goal was to make use of an often overlooked move, gravity! This team makes an offensive use of gravity, but does not rely on gravity to be successful. No one on this team is weak to Stealth Rocks, 4 pokemon are immune to Toxic Spikes, and 3 pokemon are immune to Spikes. My team also has 4 pokemon immune to Sandstorm.

Updates in BLUE

----------------------------------------------------------------------------


The Team:

Tyranitar
@ Focus Sash
Nature: Sand Stream
EVs: 16 HP / 252 Atk / 32 SpD / 208 Spe
Jolly Nature (+Spe/ -SpA)
- Stealth Rock
- Crunch
- Earthquake
- Sleep Talk

Credit for this unique LeadTar set goes to UltiMario. I believe that most leads need to set-up an entry hazard and Stealth Rocks complements my offensive based team. Having Sleep Talk is a great substitute for lum berry that allows me to use Focus Sash at the same time. Sleep Talk is also great if I can keep Tyranitar alive to adsorb sleep status. Crunch and Earthquake create a great move coverage that cover many leads.

The 208 Speed EVs and the Jolly nature allows me to outspeed standard rotom forms, so I can Crunch before the rotom will-o-wisp. That is just the max of what this set can outspeed. This set can also outspeed LeadGross, many other LeadTars and also SubPunch Breloom. The 16 HP and 32 SpD EV's allow me to take special hit more effectively such as Heatrans Earth Powers and Jolteon's Thunderbolts. The 252 Atk EV's allows Tyranitar to hit harder with his two moves.

This is how this LeadTar set does against other top leads:

Azelf - Sand Stream breaks the Sash and I Crunch turn one for the OHKO, hoping the Azelf doesn't U-turn.

Metagross - Stealth Rocks turn one. I can then earthquake turn two to put some damage on it before being 2-HKO by Meteor Mash and Bullet Punch.

Swampert - Set up Rocks and then switch to Latias.

Jirachi - I hate this lead since it always seems to flinch me >.< But I attempt to get my Rocks up, hoping to avoid the flinch since Iron Head can only 2-HKO.

Aerodactyl -I just Crunch on turn one because of Taunt and so I can break it's Sash. Then either set-up Rocks or KO on turn two depending on if I had been Taunted or not.

Infernape - If I think that the Nape will Close Combat on turn one, I survive the hit with the Sash and OHKO it back with Earthquake. If I think the Nape will Fake Out I switch to Rotom or Latias.

Roserade - I use Rocks on turn one because most expect LeadTar to be carrying a Lum Berry and don’t attempt to put me asleep, but this set has no problem surviving the Leaf Storm survive the Leaf. If I was put to sleep then I use Sleep Talk as they try to set -up which either OHKO the Roserade or sets-up Rocks

Heatran - Stealth Rocks turn one then use Earthquake as I easily survive the Earth Power. I just hope they don't will-o-wisp >.<

Tyranitar - Rocks on turn one, if the other T-Tar used rocks I often come out on top, if not then I at least put some damage on it.

Gliscor - Switch to Mamoswine turn one.

Flygon
@ Expert Belt
Ability: Levitate
EVs: 4 HP / 252 Atk / 252 Spe
Naive Nature (+Spe/ -SpD)
- Dragon Claw
- Earthquake
- Fire Blast
- U-turn

Having Expert Belt over Life Orb allows me to bluff a Scarf and often allow me to KO most switch in's. I use Dragon Claw over Outrage because being locked into Outrage destroys the point of the set with is flexibility and KOing switch-ins. Earthquake and Fire Blast is to hit all steel types, Dragon Claw is to OHKO many Dragons with SR up as they attempt to switch into my Earthquake and set-up. U-turn is so I can switch out of anything I can't hit while still doing damage.

Latias
@ Choice Specs
Ability: Levitate
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature (+Spe/ -Atk)
- Draco Meteor
- Surf
- Grass Knot
- Trick

A Scarf Latias to allow me to outspeed and KO many threats, but the Scarf also allows a fast trick to help set-up Metagross. I use Dragon Pulse over Draco Meteor because the main function of this set is to set-up Metagross and if I am left with Latias late game and can deal more consistent damage while not reducing the power of my other moves. A Specs Latias allows me to outspeed and KO key threats to this team such as 100 base Speed Dragons. The power of Draco Meteor makes it so switching in causes a lot of damage, regardless of the counter, making Metagross' and Mamoswine's sweep much more effective. Surf is to hit threats for super-effective damage such as Infernape and Heatran. Grass Knot is to KO bulky waters because without it, I don't have much of an answer for bulky waters such as Swampert.

The EVs and Natures are such to get the most offensive power and to at least speed tie with other Latias not carrying a Scarf.

Rotom - H
@ Choice Scarf
Ability: Levitate
EVs: 232 HP / 26 SpA / 252 Speed
Timid Nature (+Spe/ -Atk)
- Thunderbolt
- Shadowball
- Overheat
- Trick

A Scarf-Rotom which serves a role similar to Latias. Just like Latias this is another trick user which helps to set-up Metagross. It differs from Latias in that it attacks different threats such as Gyrados and and Scizor. Thunderbolt and Shadowball are great STAB and coverage. I use Overheat to counter Steel type threats such as Scizor. At first I ran Hidden Power Fighting to hit Tyranitar switch ins but soon found that Flygon's Fire Blast alone was not enough and needed Overheat to better cover my team. I became less concern with Tyranitar because it gives me an opportunity to set-up Metagross.

The EVs allow Rotom-H to stay alive longer and effectively counter specific threats such as Gyrados and Scizor effectively.

Metagross
@Life Orb
Ability: Clear Body
EVs: 112 HP / 252 Atk / 12 Def/ 132 Spe
Jolly Nature ( +Spe/ - SpA)
- Agility
- Meteor Mash
- Earthquake
- Gravity


The highlight of the team. An AgiliGross with a twist; Gravity. After one Agility I outspeed just about everything. Meteor Mash is a powerful STAB that hits almost everything hard and anything it doesn't, such as Steels, get hit hard by Earthquake. Gravity has two functions on this set, the first is to allow me to counter many common switch ins to Metagross. With Gravity in play, Zapdos, the Rotom forms, Gyrados and Skarmory are no longer safe switch-ins. The second function of Gravity is to set-up right before Metagross faints from repeated hits and Life Orb recoil. Gravity is a perfect way to set-up my Mamoswine.

The EVs allow me to outspeed Timid Scarf Heatran after an Agility and increase Metagross' overall bulk.

Mamoswine
@ Life Orb
Ability: Snow Cloak
EVs: 244 Atk / 64 SpA / Spe 200
Naughty Nature ( +Atk / -SpD)
- Earthquake
- Ice Shard
- Blizzard
- Stone Edge


This MixMamo set comes in after Metagross has set-up Gravity and fainted. With Gravity, Blizzard's accuracy is now 100% allowing me to hit physicals walls that may be switched in such as Celebi and Hippodown. Gravity also complements Mamoswine's very powerful STAB Earthquake allowing me to hit anything that may be levitating or flying and is not afraid of Mamoswine's STAB ice moves such as Skarmory. Ice Shards is to hit anything faster then me and KO Dragons and Gliscor. Stone Edge is in the last move slot for coverage and to hit Gyrados harder. Stone Edge is the most replaceable move on this set and would appreciate any suggestion as to what to change it to.

Offensive Threats

Aerodactyl - -I've only seen this used as a lead and my Tyranitar puts some damage on it then I switch to my Flygon to finish it off.

Azelf - As a lead this is never a problem since my Tyranitar OHKOs it. I have also never seen a sweeping variant switch in safely.

Breloom - If this gets set-up it could be a real pain. I have to get set-up before it sets-up so that it can't safely switch in. If it does switch in safely I have to just let something fall asleep and then hit it with either my flygon or Rotom's fire moves. Mamo's Ice Shard is also helpful

Dragonite - I outspeed and OHKO it with Latias, Flygon, and Mamosine

Electivire - It only has Rotom has an opportunity to set-up, and even with the speed boost Latias is effective at dealing with it.

Empoleon - I can trick it to effectively switch in Metagross or I can KO it with Earthquake or Thunderbolt

Flygon - Latias outspeeds and KO it, if I can bait an outrage then my Metagross can set-up on it.

Gengar - If it's choice I can scare it away or set-up. If not then Latias trick helps set-up my Metagross or forces it to switch if it got tricked into a substitute.

Gyarados - In early game, Rotom OHKOs it with thunderbolt. It can cause more of a problem in late game if I have not set-up my Metagross but usually it has trouble setting up a Dragon Dance.

Heatran - Latias Surf, Flygon can bait it in and KO with Earthquake, if it's choiced in any move I can effectively switch in a counter if not I outspeed it.

Heracross - Flygon's Fire Blast, Rotom - H's Overheat, and since it is rather frail I can usually wear it down.

Infernape - Flygon's Earthquake, Latias' Surf, and even Rotom's Thunderbolt can be quite effective.

Jirachi - This can be a huge pain late game. If it's not choice then setting up on it is tough. I usual attempt to trick it if it's not choice so that I can effectively take care of it easier. Iron Head just isn't fun =/

Jolteon - Flygon's Earthquake, and can also be trick bait to set-up Metagross if it's the LO varient.

Kingdra - Latias outspeeds and OHKO's it. In rain it can be much more of a problem but Metagross' defences alone help to survive it's physical onslaught and after a Rock Polish Metagross outspeeds it even in the rain. Never faced a mixed rain dance varient though which may cause alot more trouble =/

Latias - My Latias outspeeds it and if it's choice then I can bait a Draco Meteor and set-up Metagross.

Lucario - I love when this comes in on my Sash Tyranitar and tries to set-up on it while my Tyranitar is at full health =). I try to trick it to make it a lot less effective and to decide on my next switch in depending on what move it's stuck on.

Machamp - Annoying as always. I just make sure it can't get a sub up and wear it down. Rotom is also an excellent switch in if it isn't carrying revenge.

Magnezone - Only traps my Metagross and if it switch into it then that's mean I got a Rock Polish up. I also have my Flygon, Mamoswine, and Rotom - H who effectively deals with it.

Mamoswine - Can't come in safely ever, but if it finds a way to get in with my gravity up and my Rotom-H gone or my Latias not at full health then I will probably lose. Fortunately I have never had that happen.

Metagross - Rotom - H KO's it with overheat and isn't scared of any of it's usual moves (except Gravity ;D)

Ninjask - Only seen this as a lead. I just crunch it to keep it from getting behind a sub and getting a Sword Dance off. Since I always keep my Sash against these I can damage or KO whatever it Baton Passes to.

Roserade - Another Pokemon that seems to only get used as a lead. My Tyranitar usual takes care of it.

Salamence - Outspeed and OHKO with Latias or it gets switch in on My Flygon's Earthquake thinking it's Choice in which case I OHKO it as it Dragon Dances.

Scizor - If it comes in late game and I don't have Rotom - H then I will probably lose. Even worst if it's the Sword Dance with roost varient because after a Sword Dance my team is in a lot of trouble without Rotom-H.

Smeargle - Tyranitar doesn't mind the sleep and is usual able to deal with it as a lead. Never really can switch in safely.

Starmie - Starmie can do a lot of damage to my team, if it's Choice I can lead an Ice Beam and switch in Metagross but even resisted it doesn't enjoy Starmie's Special Atk onslaught. LO varients I can outspeed and OHKO with Rotom but I can't safely switch in.

Togekiss - My trick users can outspeed it and do some damage to it. Never had a problem with this pokemon.

Tyranitar - Flygon, Metagross, and Mamosine's Earthquake handle this well. If it switches in I hope it was choice or I trick a choice item onto it so that Metagross can revenge and set-up.

Weavile - Tricking it with Latias or Rotom is usual the best choice as it allows my Metagross to avoid being it by Low Kick as I set-up set's up. If it's choice then I can avoid tricking it all together and just use Metagross sooner.

Defensive Threats

Blissey - Switch in Flygon to see if it's the Thunder Wave or Toxic variant. If it T-Waves then my Flygon can take care of it, if it's the toxic variant then my Metagross can set-up on it. Trick also effectively takes care of it.

Bronzong - If it sets up trick room then I have to hope to stay alive for the remainder of the trick room since my pokemon don't like trick room. My Flygon's Fire Blast, Rotom's Overheat, and Metagross' Gravity allow me to effectively deal with it.

Celebi - Flygon's Fire Blast is usually the best answer since my team wouldn't appreciate the T-Waves. I can also trick it to lower it's effectiveness and get my Metagross in easier.

Dusknoir - Hope it's not setting up trick room >.< Rotom's Shadow Ball is a great way to deal with it though. Tricking it also allows my Metagross to set-up. I just have to watch for Will-o-Wisp

Forretress - Usual switches in on Flygon only to get Fire Blast in the face. Rotom's Overheat also is a great check.

Gliscor - If my Mamoswine is gone then this thing can put a huge dent in my team (or just plain beat it late game). I try to keep Mamoswine alive as long as possible to deal with this threat.

Hippowdon - This is just bad news for my team. I usual just hope that my Latias Grass Knot is enough or that my Mamosine is in Gravity to hit it with STAB Blizzards. Very tough pokemon for me to wear down.

Rotom-A - If Tyranitar is alive or I have Gravity set-up this is never a problem. But if it is not I have to hope the Rotom is either Tricked or Choice into one move to effectively deal with it.

Skarmory - Gravity laughs at this and if it switches in to my Flygon then Fire Blast is always a 2-HKO. Rotom is also a nice check.

Snorlax - I usual Trick it. If it's Choice Band then I can deal with it but then my Rotom - H or Latias is pursuited and KOed. A very underrated set but since it makes it more predictable I don't have a problem with it.

Suicune - I can only trick it or wear it down. If I don't have my trick users alive this can set-up and wreak havoc. Have to be careful when dealing with this.

Swampert - My options are just as limited as with Suicune. This is the reason I have Grass Knot on Latias, the only other way to deal with it effectively is to Trick it or wear it down.

Tentacruel - Earthquakes and Rotom's Thunderbolt take care of this.

Vaporeon - Fortunately I gain the option to Thunderbolt it with Rotom unlike the other bulky water types. Tricking it also is a secondary option.

Zapdos - Gravity makes this much less effective. Usually attempt to switch in on my Metagross who can set-up gravity and survive the heatwave as long as my Metagross is in good health. It also doesn't enjoy Ice Shard from Mamoswine.

You can't have a Gravity team with just one Gravity user. That's that having a Trick Room team with only one Trick Room user or a Rain Team with only one Rain Dance user...it just doesn't work!

Here, read the article on Gravity. It tells you how to build a successful Gravity team and even gives you an example of an offensive Gravity team.

I must say that this team isn't necessarily based around gravity. This teams success is also in it's ability to win without gravity in play. I am very much aware as to how to build a team completely based off gravity but my goal was to not have a complete reliance on it.

My apologies for the confusion but Gravity still plays a very key role to this team and I named it because of that. My team's Metagross is very similar to Rain Dance Kingdra who can be a stand alone sweeper without other rain dance support. If the name or statement of intent is really that much of a problem I will be happy to change it.

But thank you for redirecting me to a link and saying my team doesn't work without rating it. Your opinion will be taken into consideration. ^_^

He said in the OP that the team doesn't rely soley on gravity, I'm pretty sure he's just using it as a perk to increase Mamoswine's (and Flygon's) efficientcy.

 

[Arkeis]

But that makes Gravity more of a hinderance than a benefit. You have 3 Pokemon that are immunity to Ground, two that are weak to Ground, and none that resist it. With Gravity in effect, you essentially have nothing to switch into a powerful Earthquake from your opponent. An opponent Mamoswine can rip your team apart.

Either build your team around Gravity or don't use it at all. There are plenty of other options that Metagross can use.

 

[Nosferalto]

Hi. First of all, I'd like to tell you I like this team's purpose, a Gravity team that doesn't completely rely on Gravity is an interesting choice for a team in my opinion. I also like the fact that you have all threats covered, so I'l work on enhancing this team's performance.

I have a way of making your team a bit more offensively powerful I noticed that Latias is rather useless with a Choice Scarf attached to it. The problem is, it doesn't hit hard at all so it can be Pursuited extremely easily. Tyranitar can come in on anything barring Surf and Pursuit you, if it's choiced then Trick will provide a free switch-in, Scizor can do so as well. Also, most importantly, all of the threats it checks are already checked. With a Scarf, Latias is used as a DD Salamence and DD Gyarados revenge killer. However, Salamence is revenge killed by Mamoswine with Ice Shard and Gyarados is revenge killed by your Choice Scarf Rotom-H. The best thing you could do is slap a Choice Specs onto Latias and change it's moveset.

Latias @ Choice Specs
Timid / Levitate
4 HP / 252 SpAtk / 252 Spe
Draco Meteor / Trick / Surf / Thunderbolt

Draco Meteor's insane power will help you rip holes onto the opponents team and gradually wear them down in the beginning of the match to the point where your Late game sweepers can clean up the foe's team. DM is also an interesting choice with Gravity on the team. You still have Trick to help Metagross set-up.

This change will improve your team's offensive capabilities while not compromising it's ability to deal with threats.

Rotom-H is your only DD Gyarados check now, so I would suggest we give him a more bulky EV Spread to ensure that it perfectly checks that threat. Go for 232 HP / 26 SpA / 252 Spe for the EV spread, this way you maximize your bulkiness while the EV spread allows you to 2HKO Latias. This is a good special attack point to hit, more special attack lessens your chances on coming in on Gyarados' Waterfall and more less Special Attack leads to a Recover-Shadow Ball stall match with Latias.

Metagross seems to be your most important member of the team and the only one that sets up Gravity so that Mamoswine can sweep. However, since it is the centerpiece of the team and needs to set-up both Gravity and Agility, we need a more bulky EV Spread which works perfectly well with Metagross' natural bulk. 112 HP / 252 Atk / 12 Def / 132 Spe with an Adamant Nature will do the trick. The EVs allow you to outspeed max Speed Timid Choice Scarf Heatran, who is the biggest threat to this set. 112 HP EVs places you at 329 HP, reducing the amount of Life Orb recoil from 33 to 32 and the rest is for added bulk.

These changes aren't big ones at alls because your team is a decent one that only needs those little changes. Hope this helps.

edit: Your team appears to be a bit Calm Mind Suicune weak, so make sure you use your Specs Latias in order to beat it. It can use Thunderbolt without resorting to the SpAtk drop from Draco Meteor while sponging any attacks Suicune has to offer. This is another god reason to use Specs on Latias.

Either build your team around Gravity or don't use it at all. There are plenty of other options that Metagross can use.

The pokemon that are abusing Gravity resistence and weaknesses won't change. Since Gravity is usually being set-up only once, it will be gone before I need to send in another Pokemon and Metagross/Mamoswine would have done their job. Therefore I have never had a problem with the opponent abusing my own gravity.

Many matches I don't even need to use it or lose the chance to because I chose to KO the opponents pokemon and lose the last bit of my HP from recoil damage. That's the beauty of this team, if I see a threat on there team that can abuse gravity then I just won't use it and I still have an effective team.

If you would like to suggest Metagross' other options that would better fit this team please suggest a move-set. The one I have now I have found effective at countering common switch ins such as Skarmory, Zapdos, and Rotom. I have already mention this in the OP, so please read the descriptions not just the move set.

The other move options I see instead of gravity would be Ice Punch, Thunder Punch, and Explosion. If a Rotom form gets switch in then none of these moves will allow me to threaten it. Thunder Punch is only really useful against Gyrados/Skarmory switch ins and Gravity has done a great job to keep these pokemon threaten. Ice Punch is to avoid being walled by Gliscor but with a Mamoswine ready to be switched in....I don't see Gliscor staying in much longer. So I saw Gravity as the most flexible move option but if you have another move-set to suggest please do so.




@Nosferalto: Thanks for the rate!

And I really like the new spreads you suggested and will be sure to test them all out.

My reason for having Scarf over Specs was so that I can more effectively Trick anything with an Ice move that may out speed me and KO me such as LO Jolteon, but since I have been finding most pokemon like these to carry choice items I will probably end up sticking to your SpecsLatias suggestion =). I also like being able to revenge +1 Dragons but I may just have to lead an outrage....I'll just test out the set to see how much more of a difference the extra power makes =P

I'm definitely going to put to use your new EV spread for Rotom since keeping him alive will be much more useful then the extra firepower in case of a late game Scizor. Without Rotom I realize that a late game Scizor can really cause some damage and the bulk should keep it alive long enough.

For the Metagross spread you suggest I may use it with just a little more speed so that +1 Dragons don't out-speed me. Sometimes if I didn't get rocks down Salamence can survive the Meteor Mash and set-up a DD, soon KOing my Metagross with Earthquake or Fire Blast. But I do like the idea of adding more bulk since the longer it's alive the more damage I do. =D

Yeah I'm aware of the Calm Mind Sucuine weakness >.< I just rely on the tricks and hitting it hard with my powerful attackers. I will finish my threat list when I get a chance (Hopefully later today).

Once again thanks for the rate I'll be sure to test out the new EV spreads! =)


Avoiding the double post but I have updated/added the threat list for my team. =D

Well, you could try using 196 Speed EVs which allows you to outspeed Salamence with a DD under it's belt. It should look like this: 48 HP / 252 Atk / 12 Def / 196 Spe.

 

[Darkvirus]

If your after a solid gravity user then use Starmie as it can run a set of Gravity Thunder Blizzard and Hydropump with a life orb and never miss just using a standerd 252/252/4 spread with a timid nature so other starmie you can atleast speedtie with so once any special walls are gone it can rip apart teams in seconds

Unfortunately I would have to change majority of my team if I added LO Gravity Starmie.

Since a majority (if not all o.O) Trick users are Psychic and Ghost type, they attract Pursuits which my Trick users can lock them into. Once my opponent is locked into a pursuit (or Ice attack targeted at Latias), then I can safely switch in my Metagross and set-up. Unfortunately Starmie does not enjoy being it be Pursuit, Crunch, etc. and would have a harder time switching in.

--------------------------------------------------------------------------

I have updated my team with Nosferalto's suggested spreads. After testing them I have found them to be a very welcome addition to the team.

I chose to stick with 132 Spe EV for now but still may make the change to 196 Spe EV if they would prove to be more useful. I still prefer Grass Knot over Thunderbolt on Latias because Swampert can be a real problem and my Rotom already offers a STAB Thunderbolt.

I am still welcoming any suggestions for improvement! I will consider all suggestions so please keep the rates coming! I am still trying to make sure I effectively check the threats to this team.

24 hour bump

I would appreciate more feedback and I am listening to all suggestions.

So please, keep the rates coming!

Hello,

Really cool team, and even better that you have most common threats covered quite well. But some things, especially set up sweepers, can really become a threat: 1) SD Scizor/Lucario. If rotom got pursuited (which will often be the case) and Scizor/Lucario has a SD up it tears your whole team apart. This problem cannot be solved without major changes so try to keep your rotom hidden until late game. 2) DD Gyarados. If you give latias specs Rotom is your only check. 3)DD Ttar. After 1 DD it outspeeds everything bar rotom (which can't hurt it at all) and will ohko all 6 team members. Also with 2 choiced Pursuirt weak pokemon you can very quickly be down to 3 pokemon (as Ttar is close to a suicide lead)

Now, what could you change?
I think you should first change your Tyranitar set to one that lives longer. Ttar's incredible bulk is just wastet with Sash as suicide lead.
Tyranitar@Chesto Berry
Adamant-252HP, 32 Atk,224SpDef
-Payback
-Stone Edge
-Rest
-Stealth Rock
It will also get up rocks reliably but it can rest to restore all health lost without having to sleep for 2 turns. Chesto also beats all sashed Sleep inducing leads thanks to sandstorm. Later in the match Ttar can function as a reliable special sponge.

Now to Latias, Rotom and Flygon: Each of those 3 can work as a reliable revenge killer if scarfed. You now chose one of them to be that scarfed revenge killer, the second to be a choiced hard hitter, the 3re to be a scarf bluffer. This concept is okay, but I would change the following:
Flygon should be changed to Scarf Jirachi. It will check SD Lucario, SD Scizor, DD Ttar and Gyarados. This will be your revenge killer.
Jirachi@Choice Scarf
Jolly-252Atk, 252Spe, 4HP
-Iron Head
-Trick/U-Turn (matter of preference. Scouting or secandary trick for ie CM Rachi )
-Fire Punch
-Thunderpunch
Latias should stay your specsed hard hitter. You really should run Grass Knot to hit Swampert, Hippowdon and Ttar switchins hard. So keep your set.
Rotom-H: This thing will now be able to run a more defensive and less pursuit susceptible set. Use this set:
Rotom-H@Leftovers
Bold-252HP, 168Def, 88Spe
-Thunderbolt
-Will-o-wisp
-Shadow Ball
-Overheat/Pain Split (again matter of preference. Coverage or Recovery)
This thing provides you with a decent physical sponge and with Will-o-wisp, undoubtedly one of the best moves in today's physically oriented Metagame.

Now, if you really like your gravity Metagross set, keep it. But it doesn't really help you I think. Gravity increases Blizzard's, Stone Edge's and WoW's accuracy but you will rarely get the opportunuty to use those moves during only a few turns of effect. Also this advantage is nullified as also your foe will have that effect. For meta it could serve to hit flying/levitating foes, but all of its flying/levitating switchins get one free turn to attack while you set up Gravity (as you'll Agility on the switch) and can cripple or kill you already. You should replace it with Thunderpunch or Ice Punch and change your team's name. xD
Your Mamo set is fine and provides a nice salamence check.

Hope my suggestions helped. Good Luck !
