Can someone tell me what the best time to use your support card (Stamina or Wit) is when you are trying to learn the URA Races for the practice? I just got to the fourth race (Fifth for Rice shower) in Career and it lost the support cards. Tried recreation, tried rest, but lost every stamina. Can't get a straight answer anywhere, I just want to know which satona diamond or even maybe just a Twin Turbo?
