Zangoose, You get yourself into an awesome position like that and don't even know what to write about? xP
But anyway, write about something you're familiar with, whatever that may be. You could think of some current decks that you're a fan of and know a lot about and maybe write about that. Or possibly your own analysis on States and what you expect the meta for regionals to be like. And if you can, maybe add a little spin to it. If it's like any ordinary article you may not catch people's attention like you want to.
So yeah, I'm not expert at all but that might give you a few ideas. And if it doesn't, go ahead and actually talk to someone that knows what they're talking about! =P
