In DB you can get DarkMATTER1, which has multiplayer commands, DBPro has multiplayer commands built-in, but they're certainly not easy to get used to.
Your game idea is fine for DB, you can actually go a whole lot further, but it's good to start with something you can get your teeth into. For shuffling the deck for example, you'd simply select 2 random cards and swap them, do this 100 times and you have a nicely shuffled deck - using a simple array system will make your project nice and neat.
