Yea I know its weird, some people make ''íncomplete anime decks'' because the character only used so many cards in the anime and some of the cards that he used haven't been released yet. So yea, may be accurate but should be made playable as well.
What? The E-heroes are in the physical card game- I literally own a good few E-heroes and use them in my Destiny Hero deck. And, again, you can try branching out. Were you not listening out? You don't have to entirely abide by the cards he used, as you could literally just branch out and try out cards that would fit the character.
