Hello I am Sadamin2 but im posting as Damin2142 as my old account since I forgot both passwords but cannot really be bothered dealing with that. I decided to make a team based around Mega Latios due to its incredible bulk and ability to check pokemon very well. This team's function is to slowly wear down the oponent with mons which check alot of the ou tier and then finish off with keldeo, heatran or Latias itself.
Teambuilding Process:

Latias is here as it is the pokemon this team is centered around. Latias checks many fearsome threats such as Mega Charizard-Y, Keldeo, Volcanion, Thunderus and Zapdos however, it is prone to status conditions so I needed a monster to soak up status in which I chose

Gliscor is my status absorber and main pokemon to use knock off, it is here as my setup sweeper although that does not happen much but in many cases this pokemon took out M Gardevoir who is a big threat, however I would like to use a pokemon with more offensive presence and who can check more pokemon but I still cannot find any replacements.

Ferrothorn offers important resistances and decent special defense to take ice attacks, it is a very reliable electric check except for Manectric and spreads paralysis via T-wave. It had knock off before which is to be replaced with either leech seed or gyroball or possibly spikes. Ferrothorn is also used to punish rapid spinners and contact attacks which don't do as much damage.

Togekiss is my defogger and status remover, this pokemon must be kept healthy throughout the battle so that M-Latias doesnt get worn down too much, this pokemon replaced zapdos as my physically defensive defogger as zapdos didnt really offer much to the team and I tend to chip off opponents very well with serene grace Air Slash, but like gliscor I am in search of a bulky offensive pokemon who can replace this as I need something against Manectric and Pidgeot

Choice specs Keldeo is one of my 2 hard hitters of this team which spams scalds to threaten switches and such, it is also my late game cleaner and check to dark type pokemon. Not much else to say about this pokemon

Scarf Heatran is my other hard hitter which resists grass types and also absorbs status
Team Build:

Draco FTW (Latias-Mega) @ Latiasite
Ability: Levitate
EVs: 248 HP / 8 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Psychic
- Thunderbolt
- Ice Beam
- Recover
The main pokemon, latios functions as a very hard to faint pokemon with bolt beam coverage and psyshock (for M-Venusaur) Its max speed with timit for speed ties againts mega metagross and to outspeed keldeo. Its name is a troll which may force out switches for a quick roost. This pokemon should be used straight from the beggining of the battle, soaking up attacks and slowly wearing down pokemon to ease the sweep for keldeo and heatran.

Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 248 HP / 4 Def / 200 SpD / 56 Spe
Careful Nature
- Earthquake
- Knock Off
- Swords Dance
- Roost
Typical swords dance Gliscor which can be changed into the toxic stall one too. Its purpose is to spam knock off and handle slow defensive pokemon, 200 spD ev's to make this pokemon a mixed wall.

Ferrothorn @ Leftovers
Ability: Iron Barbs
EVs: 248 HP / 4 Atk / 88 Def / 168 SpD
Sassy Nature
- Stealth Rock
- Thunder Wave
- Protect
- Knock Off/Spikes/Leech Seed
This ferrothorn is passive but taunt pokemon can be taken care of with my offensive pokemon. Should be used to take in ice-type attacks and on physical attacks it resists. Thunder Wave is to cripple fast pokemon. Rocks should be set up first and then the defensive core of Lati Glisc and Ferro can force switches and wear down the opponent.

Togekiss @ Leftovers
Ability: Serene Grace
EVs: 248 HP / 128 Def / 132 SpD
Bold Nature
IVs: 0 Atk
- Air Slash
- Heal Bell
- Defog
- Roost
Keep this pokemon alive as defog and Heal Bell saves the team, a more physically defensive build can be made if you want.

Keldeo-Resolute @ Choice Specs
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk / 30 SpA
- Scald
- Secret Sword
- Icy Wind
- Hidden Power [Grass]
Keldeo should be brought up at the end or as a check to ground types it is my sweeper spamming scalds

Heatran @ Choice Scarf
Ability: Flash Fire
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Lava Plume
- Flash Cannon
- Ancient Power
- Earth Power
This pokemon is used as a revenge killer and can get some surprise kills as not many scarf heatrans are seen so often nowadays, plus my only check to M-pidgeot and Serperior after a few leaf storms
Threats :
Mega pidgeot - hits most of my team very hard except heatran, still dealing 40%
Mega Manectric - Just like pidgeot but can be worn down with scarftran
Chansey - Takes ages to take down and if it's in a slow stall team it's gg
If you guys have any suggestions to improve this team to take on the ladder more better I would appreciate it.
