I'll admit, I never bothered with the game after Synchro monsters joined. I'm aware of Xyz and Pendulum and Chain summoning but I have no idea how to use them, nor do I care to learn. If fur hires were released in the Vrains era then its no wonder I knew nothing about them. I just find the Fur Hires to be annoying and an easy KoG victory compared to people like me who build their own decks.
I think 5Ds are the best addition to the game since GX world was released. The way Karakuri monsters work is a clear example of how entertaining and fun can synchro summoning be
