We know it's going to be shitty for the metagame but what will actually use it well or use it poorly?
I think physical dark types are going to be cucked in Dynamax thanks to Max Darkness lowering special defense as it's bonus. Flying is also going to be really strong because it increases speed.
Charizard may actually be good this gen because it can set up sun and fix it's speed with flying attacks while running a berry to get it's health back from sneaky pebbles.
Weather and terrain is also going to be bullshit this gen because pokemon with abilities like swift swim can set their own weather reliably.
I also think Ludicolo stall teams will be common as it can set up rain for rain dish and grassy terrain and run leftovers.
