Saikyou Ginga Ultimate Zero (2013-2014) is the one I liked, it was the last one animated by Sunrise. It was very entertaining with great production value, and it showcased the card game remarkably well. The rules were clearly explained and accurate to the actual card game, and the deck selection had a really nice balance of promoting whatever set was being released that week and getting you interested in various existing deck archetypes, even weird meme decks at times
