I made a list of some of my favourite Pokemon, legenddaries, mythicals and the other tier. While I'm not looking for the best pokemon team that can demolish any team that stands in my way (i dont even like incineroar), I just wanna find niche teams that can at least be good, especially since Champions is coming. Any recommendations for a newbie? (I also like the unevolved pokemon on the list here such as Squirtle, Poliwhirl, Abra etc.) (If rlly need a reference, can use Wolfe's video on his early access to champions)
