Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I cannot even begin to describe how brilliant I think reachzero's concept is. I feel like we can do so much just with the polar characteristics of whatever we make. I think that type equalizing is a better way of achieving what we tried with Mollux, and that corebreaking is something I've never thought of before. So those three are my favorites.
These are the three that I'm most looking forward to, but I'll be fine with any of them. The only one I find meh tbh is Hazard Control, but that's just a personal thing :/
