Hearthstone needs a deck tracker directly implemented in the game.

It’s such a useful feature. You can know what a certain deck’s winrate is. You can see what decks you have been facing so far. You can also see what cards you have played so far and what cards are left in your deck. This actually gives decks an advantage over other players that don’t have this feature. Android and computer players can have this feature but iPhone players can’t? Why can’t the Hearthstone developers just put something like this into the game? It’ll just be like a button in the top right corner. You can click/tap on it and a list of the cards left in your deck, cards you have played so far, and cards your opponent have played so far will be shown. It might also have a complete battle log (all of the plays) instead of just the mini battlelog we have right now. I sometimes play another game called Shadowverse. It’s a game pretty similar to Hearthstone except there’s a lot of different mechanics (so therefore it’s not copying Hearthstone). You are able to view a complete battlelog and also are able to see the cards you have played or cards your opponents have played so far.
