I would love a Studio Chibli deck. Specifically the following titles would make great decks: Howl's Moving Castle, Princess Mononoke, Spirited Away, Kiki's Delivery Service, Ponyo, My Neighbor Totoro even Lupin 3rd: The Castle of Cagliostro. I would include other titles but I have either seen them OR don't know if a 'Grave of the Fireflies' deck would be a hot sell for anyone other than me. Possibly a variety of characters across all the films including characters from The Wind Rises, Porco Rosso or the aforementioned Grave of the Fireflies. The attached images are so iconic. I can't see anyone having a problem making cards from the I.P.
I’m in awe of the “Obey” deck. The art in those cards is stunning, makes me want to frame them and display them somewhere at home. I would love to see more collaborations with living artists, especially those that work with screen printed posters (like concert or alternative movie posters); as I believe it is a style that can translate very beautifully into a smaller canvas like a card. Artists like Álvaro P-ff, Kii Arens and Matt Taylor come to mind.
Regarding pop culture decks, I would love a Buffy TVS one.
A Narnia-themed playing card deck would be awesome—like, the suits could represent different parts of Narnia, maybe Aslan and the Pevensies for hearts, the White Witch for spades, Narnian creatures for clubs, and the magic of the wardrobe for diamonds. And the wardrobe could be an actual puzzle box that you solve to "enter" the deck or reveal special cards. Such a cool way to bring the story to life!
I’d love to see more original deck designs, especially marked decks. I really think a “Theory11” deck with their various logos from the past would be amazing, and maybe be something they could give to elite members.
