I was wondering what to do with the points and/or shards once I got rankups, as I wasn't gonna spend money on cards I don't want, and then I saw this in the Discord feed this morning.
So save them for other cards in the upcoming Nations continuation of the event.
The wording and the incorrect answers have been heavily discussed on the FUTMobile server.
As for the side event itself, most of these are there to drain your resources, so unless there is a card there that you REALLY REALLY want, skip em, like most are.
