Back to Playing Yugioh?

I stopped playing this game a few years ago probably around the time the show ended. Now i decided i want to get back into it and my deck seems completely outdated! All these "new" monsters like synchrons and tuners seem really cool but Ive never experience them b4. So, I was wondering how I should start anew. The best cards in my deck are like Jinzo, mirror force, etc all the good older cards So how should I start new with these synchro monsters and stuff. Like what packs should i buy or what starter decks. Like I was looking at youtube videos and this "frog" deck seemed cool. Also, the yussei fudo packs looked good for beginners of synchro. I may be new to this but back in the old days i was a force to be reckoned with. So help me out here and give me some ideas for packs/decks!
