the only battle card game I played so far was "Card Crawl" but it is extremely simple and after a got bored after a few games as it's also not really challenging. Was about to toss 3??? in to have the full game unlocked but I heard from reviews that it doesn't really make the game more fun.
Bought a tablet and am looking for a CCG (I never played one before but feel like I have too). I just don't like hyped stuff that you NEED to play, that's why I never downloaded HS yet but meh, might end up doing it.
