Essentially, the anime promotes the "assumed" playstyle or limits the potential of a card or deck by restricting it to the main cards of that world showcased in the anime.

It also overexagerates certain cards and decks for various reasons in order to hype the cards once they come out to the market (Variable Cord being one very good example).
