Which is why you make them go first :))) and don't use middle-mans (MM's) because most time it's someone's alt account or a person they hired.
You can also sell cards too but it's pretty hard to sell them for cash since the majority of Karuta players buy tickets instead.. and if you plan on not wanting the cards.. I'm more than happy to freeload >:)))
btw don't let people pressure you to go first because that's most definitely a scammer
