I really do hate these threads (no offence intended). You can ask what deck is good, we can answer that, but what you are really doing is robbing yourself of the opportunity to get ACTUAL match experience and skills to be able to use good decks.
So here is what I suggest you do. Go into the ELO room, play thousands of games and learn from your mistakes, become good at ELO and start making tops, continue to do that.
While getting experience is certainly a great way to become better at ELO, not everyone is willing and able to dedicate the time and effort to "play thousands of games and learn from your mistakes". Some people just want to play casually, but be able to compete to a certain extent, which I don't think requires that much dedication to UR.
Besides, it can't hurt to help a newbie, can it? :o
