On the plus side, BigAR is developing web versions for these apps that will enable cross-platform syncing. Before we begin, one quick note: All the apps listed below are designed for managing your physical card collection—they let you scan cards to create digital catalogs; translate imported cards from other regions; look up the latest rules for your game; or buy, sell, and trade cards within an app. This major release contains more than 50 balance changes across all sets. Of the three deck-building games we’ve listed, Ascension is easily the most masterfully designed. Here, you wager fake money on each round, but if you fall into the red, you will never be able to play the mode again. Deck builders? While the app version of Hearthstone falls is in the dreaded ‘free to play’ category of mobile games, meaning there’s always something new to buy, at no point do you feel like wining requires hemorrhaging real dollars.
