Pierre the Gambler's Decks

Coin Toss
Pierre plays a Coin Toss Deck. By combining "Second Coin Toss" with the ability of cards such as "Gamble Angel Bunny" and "Sand Gambler", Pierre is able to decrease the possibility of calling a coin incorrectly, thereby causing the favorable effects of his cards to trigger. If "Second Coin Toss" is destroyed, he opts not to take the risk of activating his cards' effects.

Past
During several flashbacks, Pierre is shown Dueling his childhood classmate Alexis Rhodes (episode 43). The only shown card was "The Snake Hair".
