Edit2: Only related checklist I can find which details an insert set is from the previous year, 2012. It looks like the insert set is just called "Rare" [1]?

Edit: I realized I kind of just reiterated what you already stated, sorry about that.
Looks to be part of this set [1, 2], however, that looks like an insert given the card number (#J13-R43/60), while the base card numbers are all prefixed "#J13-" with a number following (i.e., #J13-282, #J13-206, etc.). Seems a lot of work might need to be done to this set.
