Since you're starting to get into the card game, you might be interested in applying for a booster pack. It will give you up to 15 common cards.
Your account is a bit older than a month though. Usually, new users can get it for free, but you may have to pay points for it since you are just above the limit...
If you do pay points, it will be 50 points per card or 750 total for the whole 15.
