We recently implemented charts/statistics for the deck pages, i.e. mana curve, color distribution and card types. Hopefully this will get deckbuilders more insight on their brews!
Don't worry, you don't have to make changes to your decks -- we already did that for you. Also, if you're submitting new decks, you can do that as you were used to before. Everything else happens in the background. ;)
Of course, we would like to get your feedback! So, please feel free to share your thoughts and suggestions!
Extra thanks goes to Aspallar, who did the majority of work. Without him this wouldn't have been possible! :)
