New Commander Play show idea where every episode features suboptimal decks themed around a pop culture, artistic, literary or historical reference.

For example, a Studio Ghibli game with Totoro, Howl's Moving Castle, Kiki's Delivery Service, and Spirited Away.

Or the Romantic poets, but I don't know how to design something that denotes them sleeping with everyone and everything including their half-sister.

@kilnfiendpotter Haha, that's the kind of decks I usually play. I actually made a Totoro deck a while back with a lot of green Kamigawa cards. It was really bad, but very flavourful. :)
I also love theming decks around philosophical concepts (for example Thomas Hobbes' conception of the natural state or Plato's realm of ideas).
