>>31352418VGC is not banning the lower tier pokemon in open formats, it's simply the cold hard truth that they suck compared to the good ones.
Garchomp is in OU because it's good in singles. In VGC, it's worse than Lando-T in every single way. Garchomp is a bulky beatstick, while Lando-T is a bulky beatstick with intimidate, superior typing, better coverage and easy to slot.
Smogon OU for example doesn't have to worry about VGC 2015 Mega Kangaskhan. Landorus-T is a soft-check to it, because it can Superpower it for good damage and at the same time enable it on your team (Kang only has a fighting type weakness, which means Intimidate makes that weakness irrelevant).
Different metas, different examples, but at the core it's the same thing: If you allow overpowered pokemon to join, they will inevitably take the crown, because they're just better. Nothing in OU could beat Kyogre or Groudon, so if they were legal, they would obviously be on every team. Which is exactly what happened in VGC 2016.
