I have seen all these decks firsthand, and this is an amazing value offer (12 decks for $60), since it works out to only $5 per deck for some outstanding titles. The customization and artwork on the Strigiformes Owl deck is incredible, and this is easily one of my recent favourites. The Friendly Felines and Chicken deck both have very fun artwork and loads of customization; I've given away several of these decks as gifts and they've been very well received. The pair of Guard decks means you get a complete set of four gaffs that you can use for both decks, so that's a real plus, especially since the Oak deck isn't normally available for separate purchase. And the Knights deck has a great medieval feel with some terrific artwork. And they're all USPCC produced for good handling. Great deal!
