Like a good nickname, a card guard can add a little character to your Poker Personality. A fine example of this is Greg Raymer's fossil, which covered both bases as his name became "Fossilman."
To be fair, the main purpose of card guards is to, um, guard your cards. Decorative chips are a familiar option. I have a couple of those that I have either bought or won over the years. I have also been known to employ a bouncy ball at the tables. I like them for three reasons. Firstly, they are cheap so if I feel so inclined I can throw it in the pot without real fear of losing it. Secondly, they are cheap so I can chuck it across the room after a bad beat without real fear of losing it. And thirdly, they are colorful.
But this isn't about me, it's about you. If you already use a unique card card, let me know in the comments; but if you don't, I have a good place to get one--your local pet store.
Whaaa? Yes, Pets Mart...or is it Pet Smart...has a fine selection of card guards in their aquarium section. I'm talking about those under sea lawn ornaments that the fish poop on. Think about it. The gruff pirate, the glaring octopus, the "card" shark all fit perfectly with poker's aquatic metaphors. Ever hear about the fish who caught the full boat on the river? Plus some of those miniatures are downright intimidating!
