Do you have a team? I assume not?
Sadly I do not
Alright, well, what kind of team do you want? Do you like the kind that hits really hard, or do you want something that defends much easier? Maybe something in the middle?
I think I'd like a team in the middle
Try to have one really powerful 'mon, three Pok?mon that can support it, something with Stealth Rock or Spikes, and then something else to just round out the entire team. And yes PS! is a great way to improve. I should use it more often but I haven't had the time to lol.
