By and large, I am not a card game player.
All of my experience with card games comes from a brief attempt at Magic: The Gathering in high school and a lot of bored Saturday mornings with Yu-Gi-Oh! when I was too lazy to change the channel.
Random attempts to enter the genre have usually defeated me with dense rules, obtuse jargon, constant mechanic changes, and the prospect of buying hundreds of dollars worth of cards. None of these things attracted me as a potential new player.
