The game is fun and challenging, but u know what? There's one solid rule in most of my battles. I mean, when enemy is about to attack, i get only attack cards and i cant use defence, so i am receiving all dmg. Next turn enemy is not attacking, then i am getting only defence cards and i can't even damage enemies usually. it's still a miracle that i reached lvl 3 boss few times and almost beaten him... I bet its only me having that bad luck, the game is great and addictive. If u tend to have more luck than me, surely u will fall in love with this game.
