Price = "N/A"

Built a deck w Goblin Grenade in sideboard. It reads out "N/A" as the price, because apparently when it goes looking for the Last Main Printing, it doesn't skip over Arena New Player Experience as a valid set. Seems like there should be a way to designate a digital-only set so that it doesn't get identified as a potential source for price.

Also, I'd like to put in a plug here for an option on the dropdown menu for Cheapest Edition, from any printed set.

Thanks!
