[Introduction + Team Building]
This is a Uber team mainly focusing around CMSoul Dew Latios.This team tries to weaken the opponent with entry hazards,flinch-hax,priority moves,as well as taking statuses that Latios doesn't like.
At first,I figured that I needed pokemon that countered Latios's weaknesses;which were:Ice,Dragon,Bug,Ghost and Dark.Based on the new garnered information,I added Forretress into the team,seeing that it resisted all of Latios's weaknesses,and could spin hazards and set up my own.Thus he earned a spot in my team.Next,I realised that I needed a fire counter,since Forry really hates Fire moves,and usually pokemon that carry Ice Beam carry Fire Blast.Thus I thought of a pokemon that takes Fire types effectively,and I ultimately came to a decision with Heatran.And I realised something else:It also resisted all of Latios's weaknesses!So I used Heatran as a second back-up counter for Latios.Next,I needed a pokemon that countered Heatran's weaknesses.Fighting,Ground,Water.Seeing that I needed a flinch-hax pokemon at that time to flinch-hax Wobuffet too,I added Shaymin-s promptly,as it resisted all weaknesses of Heatran.Now,I realised that I needed a Ice counter,Rock counter,Fire counter and Flying counter for Shaymin-s.I already have a Ice,Fire and Flying counter.Rock types could also be handled by Forretress as he had a neutrality to rock moves,and had a high base defense to handle those.
Next,I realised I needed a Darkrai counter,since I am pretty weak to Dark Void + Nasty Plot variants.I promptly chose a pokemon that resisted Dark Pulse and had an immunity to Dark Void.I scanned through a list of pokemon,and I found one great pokemon.Primeape!It had a magnificent ability,and a resistance to Dark Pulse,and it could OHKO Darkrai with Close Combat.He was immediately added to the team.
Next,I needed a lead.I needed a lead that could prevent leads slower than it from setting up their entry hazards.Immediately,Deoxys-s came to mind.But he was rejected,because he could not deal severe damage to leads I see.I realised that Deoxys-a could do the same job AND kill leads with its high base attack stats,it was added to my team.
Thus,the team consisted of:
My lead,Deoxys-f.
My spinner,Forretress.
My sweeper,Latios.
My para-haxer,Shaymin-s.
My counter for fire-moves,Heatran.
My Darkrai counter,Primeape.
Changes made to the team:
Deoxys-a : Thunder changed to Grass Knot
Latios : Ice Beam to Roost to Recover
Primeape to Honchkrow
Heatran to Ho-Oh
Ho-Oh to Latias
Changed Deoxys-a to an all out attacking antilead
Forretress to Spiritomb
Skymin to Dialga
Spiritomb to Darkrai
Honchkrow to Scizor,as a back up sleep absorber and a counter for Darkrai all in all
Scizor to Groudon
Support Latias to normal Backup Sweeper Latias
Darkrai to Sleep Talk Kyogre
Dialga's EVs to 20 Atk / 252 Spe / 236 SAtk,with Hasty Nature as suggested by darknessmalice
Changed Groudon's EVs to 252 HP / 32 Def / 224 SDef with Careful to survive 3 Spacial Rends from ScarfKia
After all these introduction,I present you the team:
Deoxys-f @ Focus Sash
Naive Nature(+Spe,-Sp.Def)
100 Atk / 252 Spe / 156 SpA
-Stealth Rock Superpower
-Taunt Shadow Ball
-Extremespeed
-Thunder Grass Knot
A lead made specially to counter Kyogre,Deoxys-f,Deoxys-s,Shaymin-s leads.Extremespeed 2OHKOs Deoxys-f(with Focus Sash),Deoxys-s and Shaymin-s,while the combination of Thunder and Extremespeed OHKOs Kyogre.It will not lose to Kyogre due to its Focus Sash.After eliminating these leads,I set up my own entry hazards.Taunt helps me against other leads like Groudon who tend to be slower than me.The 100 Atk EVs allow me to 2HKO Deoxys-s 100% of the time,and a minimum of 30% to a standard Choice Scarf/Specs lead Kyogre.Should I encounter a Kyogre with Thunder Wave with bulk in Defense or HP,I deal a minimum of 24% to it.But,since all its EVs are pumped into Defense,it should have no EVs in Special Defense,Thunder + Extremespeed still OHKOs it.I also maximized its Speed to tie with other Deoxys-f who run max Speed and +Speed Nature,and outspeed a max Speed Neutral nature Deoxys-f.The remaining EVs were pumped into Special Attack to increase the power of Thunder.
This lead works well against the previous leads mentioned,but loses terribly against Groudon.The best it can do with Extremespeed is 40%,while Groudon can 2HKO me with Earthquake,or any other move.Focus Sash allows all the OHKOs and 2HKOs mentioned above,without it,Deoxys-f would lose.Thunder was changed to Grass Knot to ensure I can OHKO Groudon and Kyogre at the same time.Now my Deoxys-f leads do not lose miserably to Groudon anymore.Thanks ultimifier.Edit 2: Changed Deoxys-a's moveset to an all out attacking out,since I find that Deoxys-f does not have the time to set up SR and Taunt.
Kyogre @ Leftovers
Calm Nature(+SpDef,-Atk)
240 HP / 244 Def / 24 Spe
-Sleep Talk
-Rest
-Calm Mind
-Surf
As suggested by darknessmalice,my counter to Darkrai.I send this in to take the predicted Dark Void.As it boosts up,I Sleep Talk,to have a 33.3% chance of boosting,or attacking.The only problem with this,though,is the fact that Specs/Scarf Ogre can counter me,due to the fact that it has Thunder,while I do not.Luckily I run Calm,and I get 2HKOed by SpecsThunder,or 3HKOed by the latter.The set is standard.This Kyogre can also switch in to take some random Special hits from sweepers like a Palkia's Surf,Spacial Rend.Seriously though,I hate the fact that I have two weather gods in my team(Groudon being the other one).But I have no choice,I need a Darkrai counter..
Latias @ Soul Dew
Timid Nature(+Spe,-Atk)
114 HP / 204 SpA / 192 Spe
-Dragon Pulse
-Grass Knot
-Calm Mind
-Recover
As darknessmalice suggested,a normal CM Latias.I guess it works in sync with Latios as a back up sweeper,and besides,I have Dialga as a Giratina-o counter.With this,Latias can be a tank and a special sweeper.Latias reaches a wonderful 700 Special Defense after one single CM with Soul Dew.Dragon Pulse helps me against some common ubers.Grass Knot helps me against late-game Kyogre and Groudon.Recover helps me to survive longer,and Latias can use it effectively due to its bulkiness. With her incredible hold item, Soul Dew, Palkia’s Life Orbed Spacial Rend also fails to OHKO.As for Kyogre, she stands without fear as its Ice Beam only does approximately 48% maximum, allowing Latias to Calm Mind and then Grass Knot.The EVs were swiped off the strategy dex,and they do those stuff mentioned above.
Dialga @ Choice Scarf
Hasty Nature(+Spe,-Def)
20 Atk / 252 Spe / 236 SAtk
-Outrage
-Draco Meteor
-Fire Blast
-Thunder
Darknessmalice had suggested a Scarf Dialga before,and I tried it.To my surprise,it worked much better than BulkUp Rest Dialga,and thus was obviously used.Draco Meteor OHKOs a Giratina-o before a CM and Rayquaza without fail,without SR.Outrage OHKOs Blissey 100% of the time,with SR,on the commonly seen Uber CM Bliss.Fire Blast OHKOs Lucario without SR too.Thunder 2HKOs Kyogre,and I survive 2 Water Spouts from it.All in all a good decision in changing BulkUp Dialga to this little one here.It also counters Palkia very well,which is the first place I used it for.With 252 Spe EVs,I tie with Modest 252 Spe EVs ScarfOgre and ScarfDialga too.I also outspeed a +1 DD Adamant Rayquaza now.The remaining attack EVs were invested to beat the pokemon listed above.
Groudon @ Leftovers
Impish Nature(+Def,-SpAtk)
252 HP / 32 Def / 224 SDef
-Stealth Rock
-Thunder Wave
-Dragon Claw
-Earthquake
Darknessmalice suggested Groudon to counter Rayquaza.After debating over whether it was useful enough,I finally used it,when darknessmalice said that Rayquazas dont run Outrage on a SD set.After that,I did some damage calculations on Dragon Claw vs Groudon.It manages a mere 3HKO with a +2 Dragon Claw on Groudon,while Groudon can retaliate with Dragon Claw.Stealth Rock can be placed here to ensure that Latios has an easier time sweeping.Thunder Wave can help me cripple Darkrai and those pokemon who poses a threat to Latios sweep.Earthquake as a STAB move,and a good one.The EVs are to allow Rayquaza to 3HKO it at best,and surviving other random physical hits.Changed the EVs to survive 3 Spacial Rends from ScarfKia and OHKO back with Dragon Claw.I can take physical hits too.
Latios @ Soul Dew
Timid Nature(+Spe,-Atk)
4 HP / 252 Spe / 252 SAtk
-Dragon Pulse
-Calm Mind
-Thunder
-Ice Beam Recover
The star of the show,and in my opinion,the MVP of the team.After one single Calm Mind,it OHKOs everything with its perfect coverage of its moves.With the given nature and EVs,it reaches a 350 Speed,outspeeding Jolly 252 Spe EVs Rayquaza,OHKOing with Ice Beam,before it Outrages.It also outspeeds Non-Scarf Jolly 252 Spe Garchomp,and OHKOs with Ice Beam before it Outrages.Also,it can tie with other non-Scarfed Timid Latios,and outspeeds Modest Latios.Dragon Pulse can OHKO Giratina-o after one single CM.Thunder is for Lugia,whom I OHKO after 1 CM as well,and always does,since Kyogre is the most common Uber seen in the tier.Speaking of Kyogre,I OHKO it with Thunder too.Every Uber gets OHKOed by Latios.I shall show you how I deal with them with Latios:Changed Ice Beam with Recover to ensure Latios gets overlasting survivability.
Groudon - 1 CM and OHKO with Ice Beam Since I have no entry hazards,I need 1 CM and 1 Dragon Pulse to OHKO it now.
Kyogre - 1 CM and OHKO with Thunder
Lugia - 1 CM and OHKO with Thunder
Ho-Oh - 1 CM and OHKO with Thunder
Mewtwo - 1 CM and OHKO with Dragon Pulse
Darkrai - 1 CM and OHKO with Dragon Pulse,requires someone to take Dark Void first
Latios - OHKO with Dragon Pulse
Rayquaza - OHKO with Ice Beam Dragon Pulse instead
Giratina - 1 CM and OHKO with Dragon Pulse
Giratina-o - 1 CM and OHKO with Dragon Pulse
Scizor - OHKO with Thunder
Forretress - OHKO with Thunder
Mew - OHKO with Dragon Pulse
Palkia - OHKO with Dragon Pulse,lose to Scarf Variants if it Spacial Rends if I have no CM
Dialga - OHKO with Dragon Pulse after CM,lose to Scarf Variants if it Draco Meteors if I have no CM
Manaphy - OHKO with Thunder
Garchomp - OHKO with Ice Beam Dragon Pulse instead
Deoxys formes - Speed and Attack formes - OHKO with Dragon Pulse.
Defense formes - 1 CM and OHKO with Dragon Pulse
Wobuffet - I CM before it switches in,and OHKO with Dragon Pulse.Otherwise I lose the match-up.
Blissey - 2 CM and 2HKO with Dragon Pulse
As you can see from the statistics above,Latios poses a threat to almost all the pokemon in Uber tier after 1 single CM.It reaches 810 Special Attack after it,by the way.

Conclusion:
I lose to Kyogre,Rayquaza,Giratina-o,Latios,Wobuffet if Latios is gone somehow,since all of them OHKOs my whole team.
Other than that,the team has no major problems I have faced,unless I play wrongly by predicting wrongly.
This team has got me to about 1522 points in the Uber ladder.
With that,I now present this team for you guys to rate.
