So between SB sets and old 95 NAT ghosts made expendable due to new cards, I have plenty of NAT 95s that I can use for training which can turn into coins or I can save them for a potential exchange set next series. If there is a good chance that these will be worth more than the 12600 training I can get from them now I'll hold them but if the likelihood of them being useful is low or they will probably not be worth much more given how people used the gingerbread sets last series then I'm better off just taking the training now.
