Already we're all aware gambling is a game of luck and fortunes yet people do debate skills and strategies you can use to win gambling games by conducting research and experience and we've heard of those people who claim it worked for them. My question will be, can a magic spell influence the chances of predicting accurate gambling results?
The magic tricks in real world are tricks of hands, misdirection and illusion. Surely you can use them on physical gambling but it would be cheating and if caught you could face problems. There are no other ways of doing the magic. There are some skill based things you can try but they too are considered cheating (card counting) or still won't increase your odds significantly (reading opponents body language in poker). Gamblers do believe in some superstition or a lucky charm but they too are just a placebo. Whether you chant black magic words or wear red underwear, the gambling would always be a game of luck. Just do it responsibly.
