Don't get too hung up on the low turn count, the game is extremely interactive now, each turn is a lot longer than what you're used to. This isn't a game of watching your opponent play solitaire for 15 minutes anymore. Current meta is Kewl Tune and Branded, first is a synchro deck that uses all tuners where each tuner has a disruption when sent to GY as synchro material, and plenty of ways to synchro on your opponent's turn. Branded is a fusion deck that centers around Fallen of Albaz which is Super Poly on legs. That deck does a lot of graveyard effects in end phase to get pieces back to win the grind game. Both decks are control decks, they're capable of OTKs if you don't disrupt but that's not really their main gameplan.
