We’ve just spotted a new full art promo for Boss's Orders (Cyrus) in Pokemon’s official CardDex app! It’s SWSH251. The card hasn’t even been revealed in Japan yet. It’s illustrated by the legendary Mitsuhiro Arita.
There are currently no announced products that we know of that will include this promo. It might be tied to a product releasing early next year, such as one for the unnamed SWSH12.5 set. It’s also possible there’s an unknown product on the horizon that we simply haven’t heard of yet, such as a store exclusive. Store exclusives don’t usually get announced until the last minute. Either way, we’ll find out what’s going on soon!
