Having spectated a lot of games on ladder and fought MLT players on my alt for video, I think I can post on this thread about what I have seen on the ladder so far in MLT.
To preface there are a ton of flying-type teams on the ladder mainly HO variants. Below I have posted the various variations of team I have commonly seen and some sets that are surprising!?
Flying-type teams:
Permission from chaitanya to talk about this team. This variant of Flying was used by chaitanya and has very good offensive tools to catch you off guard. The teams boosting core of DD Flyinium Z landorus-T and DD Lum Berry Dragonite showed its potential on the ladder as many players struggled to deal with this core. The team also has some form of defensive backbone in Celesteela [Sp.def] and pivot Rocky Helmet Tornadus-T with Defog. Mega Aerodactyl is Taunt, Stealth Rock with EdgeQuake combo for overall good coverage and lastly the Thundurus-T set saw some changes while laddering, at some point it was Choice Scarf with Grass Knot and later got changed to Agility + 3 attacks set with Metronome as item. Overall a great offensive team for the ladder.
This variant of HO saw a lot of usage on ladder from many MLT players. Nothing much to say about it since the team tries to cover as many matchups as possible with its squad. good team to quickly pass low ladder.
Similar variation as above however slight change of sets and team slots here. On this team it is Sub SD Hawlucha while the above one has DD or Agility + 3 attacks Thundurus-T. On this team, Dragonite runs a DD set with Dragonium Z while on the above variant it runs a Band set.
This Balance variant of Flying also saw good usage in week 1 in my opinion and it is pretty solid. Landorus-T is Speed control of the team with Rocks while Gliscor and Zapdos take the Defogger role. Band Dragonite and Mega Charizard Y wallbreaker core and defensive Celesteela to wear down teams.
There were more variants of Balance Flying on Ladder with Mega Charizard Y and Mega Aerodactyl.
Ground-type teams:
For Ground-type teams, I noticed Mega Steelix making its appearance on even sand Ground teams to counter the Fairy teams running around. Here is what the team composition looked like:
and then there was also this sand less Ground team :
This team has Clear Smog Gastrodon which allowed the team insurance against some common threats on the ladder such as Kommo-o with Kommonium Z and Z Celebrate Victini. This is my team actually and here it is if anyone wants it:

Water-type teams:
I have seen a ton of different variations for Water on the ladder considering the fact that it is one of the most versatile type on the ladder. Here are some of the teams I noticed frequently:
Balance teams with Volt-turn core are pretty common now in my opinion but some teams went a step ahead to have a surprise factor and utilized Choice Scarf Rotom-W with Thunder Wave to catch threats like Kyurem-B while also compressing the role of a Defog user, this allowed Greninja to utilize moveset tailored to the teams need, some teams used Choice Specs greninja while others used Expert Belt.
Rain teams with decent defensive cores between Sp.def Empoleon and Toxapex are also pretty common as this allows the team with good utility support and frees up the slot on Mega Swampert to make it AOA set.
More offensive variants of Rain teams with Crawdaunt or Primarina / Azumarill made appearances here and there.
Noticed Kingdra being used again on Rain teams due to the low usage of Mantine. I saw 3 different sets for it on the ladder.
* Choice Specs * Sub DD with Dragonium Z [Saw usage in MPL too] * Agility + Focus Energy Cridra e-e
some more interesting sets which I noticed were Choice Scarf Primarina or Tapu Fini for the Dragon match up and CM + Block Mega Slowbro.
Steel-type teams:
Apart from the steel team Sabella posted above, I have also noticed good old steel teams like Klefki offense and priority spam steel.
Electric-type teams:
Nothing too interesting here to see, I just saw a lot of standard Electric with Alolan Golem or sometimes Magnezone over Alolan Golem. Sturdy Custap Berry Explosion Alolan Golem saw some usage on ladder with its pure HO like archetypeand I also came across Mega Ampharos Electric team..

Dragon and Fairy are getting a lot of usage and its mostly the standard teams for them however I saw some slight variations like on Fairy where Clefable ran some Cosmic Power + Calm Mind set.
Conclusion: Having shared what I have seen so far, I am eager to know more from other players about their experience and the different sets / teams they faced. All the best.
