Check-Out (Mechanic)

To check-out, roll two 6 sided die until you roll the number of a book you do not currently control,
then create that book
I'm sure I'd have to write several lines of clarification, but the overall gist of the mechanic
is to create artifacts of varying strength. More probable die rolls are somewhat weaker. One
book is mostly downside (roll2), so players will
have to choose if they want to keep checking-out
and risk getting it. Roll 12 and you can choose.
