imagine we're building a castle out of playing cards, and every card is like a secret blueprint, guiding us to where the next card goes. but suddenly, we find a card that seems a bit out of place, like it has a wave aside command hidden within its design, compelling us to ignore all the pre-existent rules and start again with a new foundation. this card is special because it whispers secrets of how to construct such a castle in a way that reveals hidden, undercover flaws within the structure itself, making it look magnificent on the outside but frail and deceptive on the inside, ready to collapse at the slightest touch.
