When I'm not, (or cannot 
) play Minecraft, I often (over)indulge myself in this competitive Pokemon simulator. For those unfamiliar with it, it basically lets you get any Pokemon you want, with any moveset you want, and you can battle without worrying about EV training, breeding, leveling, or anything like that. There are different tiers and metagames, Pokemon can only be used in their tier or above, that way you can't use anything too strong in a weaker tier. Then of course there's Ubers, where nearly everything goes.
If you're interested, feel free to challenge me, my user is whiteNnerdy234, I do Ubers and 1v1, with the occasional Random Battle.
If there's enough interest, I will gladly show off some of my Ubers replays as well.
