I've seen a few teams but I really don't know, it seems pretty open right now. Some of the teams that I've seen people talking about are the capture team, the bug team , Iron man team, S/V, gauntlet or belt team . What has everyone been winning with?

Superman...and Superman...

It's a tough question. Look through the "What did you play" thread (I think that's the name) and see if you can find the Modern Metagame thread. Everyone's Meta is different and a lot of times people don't focus on the creation of GenCon teams too hard until after Retirement.

Or you could PM Massu or Morand, or Vlad or... blanking on names. But those guys make some decent teams I hear.

300 point team I have wanted to play recently:
Superman 150
Flash 105
+UB 12(suit of sorrows + what ever you want)
donald blake 33
300 even

2 hss super strength characters seams pretty good and with the +2 stats you can be a big threat with the flash. DB provides reliable support rolls, but Idk if this team would do well.
