Disappointed to say the least. Cards are up to date, however gem cost to gems earned are supremely out balanced once out of initial start up. The game constantly crashes while in solo, online duel or in deck build. I play several games that use moving parts all day long but this game is the only one that just closes at any moment. Points to create cards to dismantle is out of balance and only getting 4 designated cards out of special packs for 1000 gems is way too much. Change these please!!!
