Yeah, to be fair, a lot of stuff chews through breloom. I've just seen it used more now than in 5th gen for some reason. Basically, you just rock tomb when something tries to switch in, and you outspeed on the next turn. But really, breloom was broken in 4th gen before the speed creep. There was this one time that my friend and I were at this social event where there were a bunch of kids and video games. Someone brought PBR and everyone was battling each other on PBR via their HG/SS and D/P/PT games. Oh course, you know these kids were all using event pokes and all the legendaries they could scrape together. I got called out since someone said I was pretty good at Pokemon. I accidentally selected only 2 pokes instead of 6, a breloom and a metagross. Needless to say, I made some little kids rage, sweeping their teams of Groudons, darkrais, and mews with that stupid substitute toxic heal breloom with spore, substitute, seed bomb, and focus punch. I know I shouldn't take pride in slaughtering thee twelve year olds in Pokemon, but man.... It was great.
