I play Magic, I have a budget BWR warrior deck that I want to build on some more.
Your site does not really seem that attractive, the extremely narrow style of the site and big font, as well as the use of buttons, especially on both sides make it seem very cluttered, the banner also sticks out by a few pixels, also using two of the exact same picture of a pile of cards is not the best either. Make the site wider and change the buttons to either pictures or just normal hyperlinks. The colour choices is pretty oldschool, the blue of different kinds does not really feel like it would attract people who play Magic a lot, consider something lighter, and more fresh, a fresh and modern look will attract a lot of fresh people, and will make your site seem more legit and clean.
