An example of a Collectible Card Game is Babylon 5 by Precedence. The masters of Customizable Card Games are undoubtedly Decipher, with Star Wars CCG, Star Trek CCG and others.
An interesting thing to note is that Magic: The Gathering (and every other card game by Wizards of the Coast for that matter) is not a CCG -- it's actually a TCG; a Trading Card Game.
