Hmm, there are sooo many tiers in this community, and I've only tried such a small sample of them.
I dislike playing the game of favorites, but can't I still say what tiers I've felt attached to as of late?
So far I've mostly been trying to engage in Gen3 OU, as I'm also playing cartridges of Fire Red and Sapphire and trying to build an in-game competitive team!
Before that though, I played Gen 6 UU, Monotype, and Gen 4 UU as well.
Oh~ and it seems I've been taking a moderate shining to [Seasonal] Super Staff Bros. too. Is that considered a tier for the sake of this discussion?
