If you're still looking, I would like to play some battledome.
I'm pretty good with a bow and I can hold my own with a sword. Putting those things together, I can quite honestly kill all but the very best.
I've never tried bases, but we only need one guy on our team to do that.
I've always gotten a full set of iron, smelted and ready to go with at least five minutes to spare. I suspect I could gather more, but in all the other teams I've played in a was the PvP guy, so there were others who collected iron for the builder and whatnot.
If you need me to be the iron hoarder, I think I could do a decent job.
I'm 16, by the way, and I play Minecraft only when I am on a team like this, to practice and to play the actually competiton. I'm fine with playing with nearly anyone, unless all you want to do is mess around. If it's a serious game, I don't want to be apart of that. On the other hand, if it's a friendly competition I have nothing against a little fooling about, as long as we win anyway :D
That's basically it. This is all said assuming you're still looking.
