I have my own reasons to believe wild format is superior, exponentially. What I consider to be the best card game in existence, totally is challenging and has it’s own e-sports circuit. People like valve and blizzard, which is coming under ownership of microsoft, wholly are the reason e-sports exist. For something to be competitive, there must be fair rules and guidelines. Hearthstone is a professional-worthy game. But the question lays in the backburner of every moldy flesh lying on jupiter – which format is the hardest to compete in?
Wild format is for the truly adept in circumstance.
