My point was that because of when they start and end the event it is only possible to get 165 crystalis without dozens of puddings and the card cost's 175. The last one costed about 160, so if you were an insominac like me it was possible to get the card without spending money.

Edit: Nevermind, I did fuck up the math. 180+10 is the maximum free crystalis. I figured for 5 full days of rewards instead of 6.
