What up!

I've been playing 12 post for more than 6 months now we succes, i've played anything from the UG list, Bonfire madness, Mono G and so on.
The thing is that i have a pretty big event comming up and i cant decide on what to witch build to play.
I expect to see alot of: D&T, BUG, RUG, Elves, Miracles, Combo ( Storm, Omni ) and other TNN based decks. right now i feel like the UG list with main board needles are the best choices and a counter heavy sideboard.

What do you guys think ?
Would be nice with some help on the sideboard aswell :)
