Also, the game is purposely difficult which forces you to upgrade cards which costs way too much, or buy new cards with premium money, or spend gold to level heros. The grinding would take forever just to get gold and booster (fodder) cards to upgrade your cards, and the game hardly gives gems (premium currency) which is the only way to get decks after you get past the tutorial free cards......
So, grind forever and still lack cards after all of the grinding, or buy gems with real money so you can buy decks and convert gems to gold to level heros and upgrade cards....
This game is P2W, the quests only give you a basic set and 1 or two extra cards for each hero, which is meant to make you buy overly expensive packs with premium currency (which the game doesnt give enough of). So, for example, even after about 4 hours of game play you will only get a few free packs which are meant to give you the bare minimum to barely build a deck, and then you still wont be able to buy a gold pack, only 1 silver pack (which is 3 cards only).
