>>33926364Yugioh is a card commercial, but it's not entirely about cards. Every series goes off the rails and becomes a weird monstrosity with card games. That's what the series are all famous for.
GX became Evangelion and the protagonist went evil and married a demon. 5D's was the most grounded, but it became an environmentalist science fiction piece. Zexal became Super Saiyans vs alien ghosts who practice human sacrifice. ARC-V tried to be a feel-good happy show about overcoming the odds, but then became Madoka Magica, if Madoka directly killed people.
