Those who give this game low rating probably dont know the mechanincs of the game of course its given that the first few weeks or months new players will have a diffcult time having some of the cards but you just need patience and time and eventually you will have them. daily missions gives a reasonable amount of rewards and the story gives you rupees too so do it and you can rake 15,000 rupees or more by the next expansion. PS. YOU CAN CREATE CARDS USING VIALS YOU FOOLS
