Game development - Data question

Question

Hello, thanks for taking a quick read,

My current goal at the moment would be to develop a card game, (similar style to yu-gi-oh), with this style, there is many cards to pick from, and with each card, multiple stats, I.E, CardA may have 50 Attack, 20 Defense, 100 Health, and be worth 1000 Gold. That is simple enough to hard code write into a C# windows form application, using classes, but my overall goal would have 100+ of these cards. Entering each individual stat of each card seems... messy. I have been doing some reading on .XML files as a form of a database, as well as C# Databases and finally MySQL.

I am unfamiliar with all 3 database types and I've managed to become lost in the internet on what to read. I am hoping some one may be able to recommend some sort of database to me, so that I may focus and read more on that specific type, and be even more generous in giving a rough explanation and general use of each one. I'm currently using Visual Studio 2010 as an IDE.

Thanks
