Honestly, I think it's mostly nonsense. I don't believe a lucky object or a ritual can change the cards or the outcome of a hand. If playing with a tennis ball or a fidget spinner helps someone stay calm and focused, that's fine. But I think the real advantage comes from making good decisions, controlling your emotions and understanding the game. After a few bad beats, it's easy to start looking for some kind of luck or bad luck, but in the end, poker is about probabilities and decisions, not lucky objects
