大クトゥルフ発狂大富豪 (Cthulhu Mythos Madness Daifugō)

Cthulhu Mythos Madness Daifugō is a high-chaos climbing game that grafts 25+ global house rules onto a Lovecraftian nightmare. Players battle with a hybrid deck (standard cards + 25 insanity-inducing originals) as new rules actively corrupt gameplay. One round you're collecting tricks-the next, you're sacrificing cards to Cthulhu or losing points for saying the word "fish."
