I just started playing this myself and I'm a little clueless. I see a lot of potential in it too though so I'm going to spend $500 on opening packs that you can follow along on my blog. But I do have a few questions:

• Is it worth it to combine cards to level them up?
• Gold cards - Are they harder to get than legendary cards? Basically what's the odds?
• Will there be any new cards before the tournaments start?
