Yes. I had such a talisman. A local witch gave it to me. Said it for luck in the game. Then I lost it. I don't know if I played well or if it was a mascot. In any case, at the level of autosuggestion, this is a good option for improving the mental state.
When my cat is around, he may get good letters. The bad thing is that the damn cat is always hidden. There are few times that he approaches for a caress. Consequently my game of poker is so horrible my cat's fault. Hahaha
5 years ago I was at the horseshoe in Baltimore. I won a lot of hands in a row, so the guys told me that I had a lucky charm ,,, a Japanese bet on my hands too and so he won and shared a part with me ... besides paying me 6 beers ... I won 550 dollars the first time live. It was exciting !!!
Playing on-line poker, I don't have a lucky charm or anything, as Luck comes and goes just like money, You either have it, or you spend it, Live games in Casino's I do use a Card Guard, I have several, and the one I use most has a Gold coloured back, with Pocket Rockets on the front.
I was once approached by someone at a game who said he knew my tell, and that was every time I played a hand, the Card Guard would be Aces up when I played an Ace hand and Gold side up when I played suited connectors, or a small pocket pair.
I never paid much attention to how my Guard was when I was involved in a hand, and when I was not involved, I would spin it between my fingers, or on the table, so it went on my cards whichever way it landed, but after him saying this to me I used it to my advantage when I came up against him in a hand, and even when I saw a Flop with an Ace on it I would look at my Guard and say "Careful now! Aces up" and he would fold even before I made a bet.
