From my experience with game-based anime which you can actually play like Yu-Gi-Oh and Bakugan, the rules of the game in the anime is vastly different from that in real life game. For example, 1st season of Yu-Gi-Oh didn't require sacrifices for stronger monsters, and Yugi didn't automatically win by having a single piece of Exodia. In the Battle City Arc, when Joey fights a Rare Hunter, he has 3 of every piece while the rules state you can only have 1.
Since Cardfight!! Vanguard is in a way like Yu-Gi-Oh in which it has a real life card game (not sure if the anime is based off the game or vice versa), I am wondering if the game rules of Cardfight!! Vanguard in the anime is the same as that of the actual game itself?
