Apologies to both b76 and Wings of Night for taking so long with these requests.
Wings of Night's Request: Mega Medicham + Hydreigon
Since Mega Medicham and Hydreigon are both kind of slow, I wanted to utilize a Mega Medi set that would put more pressure on offensive teams. For this reason, I opted for an Adamant nature with dual priority and the standard HJK + Ice Punch. Hydreigon is Modest with Dark Pulse for its primary STAB attack with Flash Cannon and Earth Power to round out coverage and Roost to give it some longevity. Forgoing Roost for Dragon STAB is an option if you don't mind Hydreigon only being able to fire off a few hits. Next I added Magnezone for its Fairy and Flying resistance and its ability to pivot. I believe Scarf is optimal here considering both Hydreigon and Medicham are slow and really appreciate Zone's ability to pressure things like Keldeo and the Latis. Clefable was a pretty obvious next choice considering the team was quite weak to the Latis and Weavile. I opted for Old Faithful AKA CM + Twave because it is an excellent wincon and para spreader. Next I needed a Rocker and sand check, so Landorus-T fit well and made a solid VoltTurn core alongside Magnezone. Lastly, the team was in need of something that could switch into Keldeo fairly well, so I opted for a Latios. Originally, I had Defog, but the team isn't too pressured by hazards, so I changed it for CM to help against opposing Clefables and Psychics. If you want a bit more bulk, I suppose swapping Latios out for Latias is an option, but I think the power is nice. Overall, I think it's a pretty solid hard-hitting balance team. Sorry again that it took so long for me to build it, but hopefully you like it!
b76's Request: Mega Alakazam + Keldeo + Bisharp
Mega Alakazam, Keldeo, and Bisharp form a pretty classic Psychic/Fighting/Dark offensive core. For Mega Alakazam, I wanted a set that had the most cleaning power possible since Keldeo and Bisharp are great at punching holes in opposing teams. Psyshock is the STAB move of choice to help against AV Torn-T and opposing CM users while Focus Blast and Shadow Ball are pretty standard. Next, Keldeo is Specs as requested while I only changed out SD for Pursuit on Bisharp because it's generally outclassed in the role of a trapper and would rather try to sweep with boosted Sucker Punches. I also gave it a Lum Berry so that the team isn't quite as weak to Rotom-W or Scald burns. To go along with the core, I wanted a sweeper that had a lot of versatility and could capitalize on potential weaknesses such as Thundurus or Excadrill. I choose Double Dance Lando-T with a Yache berry for the slot. Next I needed a Rocker and more solid Talonflame check and Fairy check, so I opted for Heatran. The team had a huge weakness to Water types in general and was still a little weak to sand, so I selected AV Tangrowth for the last slot. It synergizes well with Heatran while being a nice blanket check for most waters. Once again, apologizes for taking forever. Hope the squad works well for you!
