Nice joke. They are going to release e hero and other hero support cards as long as they can make money.
Why do you think they spread the e hero cards in multiple boxes? Not because they are competitive, but because they are a fan favourite.
Apart of the obvious cards (Absolute Zero, The Shinning, E-call and Stratos...) what cards could you possibly put to make them competitive? Just asking because those one are the cards that can make the archetype good.
Nothing really. But I fear we will get to the point where even those are no good. I don't think they want elemental heroes to be higher tier meta. But when it is too late, you can barely even enjoy casual duel with all the forced disconnects.
