@TenshiHikaru, I'm glad to hear you're getting into the game as well!
When I started out, I watched YouTube vids until I had a good grasp on the rules and the basics of deck building, then when I thought I had a good idea for a deck, or a specific deck I wanted to build, I took it to the deck garage forum and tried to get as much feedback as possible or simply read thru articles about other players playing/testing/building the same deck as me. The Beach has been an incredible resource.
Then, when you have a build you like, register for the monthly tournaments. You will learn more faster by playing against players who are better than you, and the competition level here is great. Don't be afraid to chat with opponents during and after matches to get tips, insights, and advice. Almost everyone I've come across here as been super nice and extremely willing to share their knowledge. Good luck and have fun!
