Synchro still lack of support. Personally i don't think synchro will be competitive until Konami decides to releases better tuners or more generic synchro monsters
I have Sabers ready, but I haven't tested much in PVP, I lost 3 out of 7 for the stamps, so I need to work on a better build. That level 9 Generic synchro was a good start, but I agree we do need more support to make them more viable. For the time being, I think Akiza's skill would be one of the most useful as it gives us Black Rose Dragon and two level 1 tuners, also Mind Scan and Cyber Style.
