Change grandmaster level name to be impossible. Cause it is not possible to complete your grandmaster level in this game.... In grandmaster... How can you complete if you will not find a card in deck... Required card... Like in treepeek and so on.... For making grandmaster level impossible game do no provide you a required card..... Means...you are in playing good but one card is missing.... Shuffle is worst in grandmaster level.... They made it impossible for removing required cards from deck
