I would not play. It is too risky. stuff like that can wipe off one's entire collection, as you know Ryan.
Yes, I realize that if it is a virus or other disease, then the whole collection could get wiped out. However, until I determine that's the case (barring any decline in health), it will get a chance at life as everything else in the shipment should show symptoms soon since they were all in the same shipping crate after all not to mention they all came from the same seller. All the new ones are separate from my personal collection as well, so there's no issues there either.
Also, the seller issued me a refund for it as they said they sometimes have babies that turn out that way.
