They should make it like in the dungeon runs, use your heropower x times or gain x armor or play x games to unlock hero powers or treasures. But so we have to collect 100 cards from the new expansion or x epic cards from old expansions to unlock treasures ... Duels are fun but i also don't like that paywall.
When i left school you werent born yet boy, good luck for the next time

XD Maybe in his age they used to do math with pencils and paper and the teacher always told these guys they would be something in future xD Imagine his teacher seeing what he becomes? A White Knight defending a greed billionarie company using the argument of "MATH" to do so xD
