If you want your very own D/D/D deck then this Structure Deck has all the basics. You get to play around with Pendulum, Synchro, Xyz and Fusion in this deck. You have to get the 2016 Mega Tins (both Kaiba and Yugi) to expand your Extra Deck collection and a chance for more D/D support cards. The best booster for this deck would probably be Dimesion of Chaos as it contains important D/D and Contract cards.
With the upcoming Yu-Gi-Oh! VRAINS, a new rules such as Pendulum zone location change and a new summoning method called Link Summoning may hinder this D/D/D deck, but Konami will likely release new support cards that would integrate Links in this Deck.
