I played my first game today at my local gaming club/pub and I think I'm hooked. I've always enjoyed an element of competitiveness to my card games, and I think A:NR will scratch that itch quite nicely, plus it turns out there's a growing competitive scene at one of my FLGS, which is always fun. Now I'm looking to get started and I need some advice.
Is it worth it to get 3 copies of the Core Set? I understand that two copies nets you 3 of most of the cards, but are the last remaining few worth another set for? Also, as each expansion comes with 3 of each new card, is it ever worth it to get more than one copy?
