Teambuilding process:
I was trying to build a team out of Mega Latias, and I figured out I'll make each of the mons to check one another. We first have Defensive Latias-Mega, which has Psyshock and Thunderbolt and can check Poison and Water types for Clefable, Hippowdon and Excadrill. The purpose of this mon is to be able to balance out all the weaknesses the other sweepers have. Skarmory is added as a spikes setter, to annoy a lot of mons in the Meta, like Manectric-M, Tapu Koko and Heatran. It has Brave Bird to ensure it's not completely tauntable. Clefable creates a good core with Latias, both having TWave, crippling common checks to them like Jirachi and Tapu Lele, as well as being able to Wish onto Latias when it gets low. Keldeo is an MVP in this team, as it helps check almost every single threat to the team, so it must always be kept alive. Scald and Hydro Pump are its main STAB moves, removing the Ground and Fire types before Excadrill comes in to sweep, Secret Sword can kill one of the most threatening mon to the team: Greninja (Sharpedo and Crawdaunt, too) and Stone Edge can remove Zard Y and Volcarona, which is another huge problem to the team. Excadrill and Hippowdon are another core, Hippowdon having Sand Stream and Excadrill having Sand Rush. Hippowdon is another tank, also able to get Stealth Rock and Toxic on setup sweepers. Excadrill should sweep only all faster mons are cleared, like Greninja, Speed Boost users and Scarf Users. Most importantly, never let a Will-O-Wisp land on it, as it is a Toxapex clearer as well as a threat to Koko and Zard when Sand Stream is up.
If you have any suggestions please just tell me! I'm a pretty new player, and I'm still stuck trying to get to 1600.
