The fact that you're playing for opening tricks is the reason you're only rated 1200. Play conventional openings. Use the opening to reach a playable middle game. Do lots of tactics puzzles and learn about endgames.
That will help you win more games than any change to your opening repertoire.
Something that people at ~1200 USCF have never heard of, that can have really strong attacking chances (Preferably when they have studied it a bit as well). I've tried the reverse Leningrad (Polar Bear System), but I want to expend my repertoire, since I face the same people a lot in my local tournaments and they might pick up on my tricks.
