Pay to play. Full of little lies. To complete a deck (quicker than months of grinding) you must pay. They say an event will end on a certain date at midnight, when they really mean the day before at the stroke of midnight. If you invested tons into an event and you get fooled: you get nothing. In fact, often you get nothing. Unrewarding, fundamentally flawed card game. It's got a pretty ui but... Play something else.
