Guess everyone winds down after a while. I was the same way, back then, when I used to post (crappy) suggestions in the CRMT, and had a League running on this site... Then I took a 6 Month long break from this site and the internet in general, then finally came back and began posting in the InGame RMT. Man, takes me back... But anyway, I know what you mean. It's a little wierd at first.
Making a team is not easy. First, you need to think of what you team your team to do. I decide my lead first and base my team around that, in a way. Second, patch up common weaknesses with the appropriate Pokemon while keeping the theme and roles of Pokemon intact.
As in, It seemed you were talking about how Magnezone wouldn't be a threat to your Metagross (which it might actually be), so I was simply clarifying that was talking about the Pokemon Metagross as a whole.
