Virtual expansions, or "dream cards" are created and approved by a players committee known as the Watchers Council Association.

They are also responsible for worldwide player rankings, current rulings, and tournament organization and support.

Players compete to be the first to successfully either earn 10 destiny points, or control Sunnydale Park for 6 turns.

This means, for example, that when the main character is a hero, minions and villains cannot be included in the same deck.

The 200-card Buffy the Vampire Slayer Collectible Card Game base set is known as the "Pergamum Prophecy".
