You save gems for months. You reach the cap (first insult) of 9999. You save over 12k, but you only have a certain time window, after which everything above 10k expires (second insult). And then, after saving up and timing everything, your 12k gems aren't even enough for the CORE of a new deck from a MINI BOX!!! (4xUR 5xSR) Meanwhile in master duel (also Konami) 5k gems can be enough. Meta is boring due to constant nerfs. Only play this if you enjoy being manipulated into spending money. RIP DL
