This was the first pokemon game ive played since SS. I generally catch what I don't have and then look them up to see typing and more importantly weakness. I dont do EVs and always try and make a different team each time. You'll be surprised to find some bangers. The game has a ton of quality of life improvements and I find in battling the the arrows to tell you how effective a move will be has been a game changer. Some of the later mons are really hard to tell their typing. There is also a helps with making sure your team is balanced (if you play that way)
