Forum:Need help with my deck plz

Hi, I used to play yugioh but HAD to quit about 3 or 4 years ago. I was an avid player and still remember the rules and everything (I was an AVID player and buyer).

I just recently bought the "Rise of the Dragon Lords" deck and it started out great, but when I started playin against some higher end duelists it seemed I had reached a dead end.

Because its been so long since I last played the game, I have absolutely no idea as to how to improve my deck based upon all the new cards I haven't kept up with.

Some Ideas I have come up with on my own is maybe creating a dragon/machine deck with the cards I already have and the Cyber dragon cards. Another Idea was maybe combining THAT with the new tuner monsters. Perhaps the Crystal Beasts cards?? maybe level cards too.

All in all, I don't have a clue where to start. Any advice you can give would be much appreciated.
