...asking how to get luck...honestly.
Basically in the long haul, there is no luck. Just statistics, probability and 52 cards. Play more games. Then ensure you play sound strategy. Bad luck is just a variance hit on the lower probability actions. If you have an 80% chance...1 in 5 will lose. And if you only play twice and you lose once, you've lost 50% of the time when the expectation is 80%. PLAY MORE. At low volumes, you cannot trust the probabilities. Its the long run in which a strategy pays off.
If that doesn't work, try all the stupid things superstitious people try, spending lots of money on it in the process. And for $10K, I can send you a custom built luck funnel.
