The Arena only sets are missing from edition/expansion list. Although those cards have $0.00 trade value, it messes up import/export to arena (since those cards don't exist in any other set. Arena Beginner (ANB) set includes 116 unique cards which are fully legal within Arena. In reading through other posts regarding virtual card support, I think (and I could be wrong) but making "Virtual" a card condition (and less then Bad so it doesn't affect conditioning) might be the easiest solution. It'd need to set value at 0% since arena cards can't be traded.

*For MTGO users, there already is a viable workaround for virtual cards, an "other" deck type as a binder. MTGO fully supports exporting to XML which can be displayed in an easy to copy/paste format, this is why I am not suggesting full virtual support, only adding the virtual-only sets. With instruction, I can compile the set lists/images without a roblem.

These are all the sets that are Arena only:
