This is a test of your knowledge of Yugioh. Be careful: SPOILER ALERT!
PS: If you're wondering what D.MOC is from question 5, it stands for Dark Magician of Chaos. Magician of Black Chaos and D.MOC are different in two ways:
1. DEMOC isn't a Ritual Monster, unlike MOBC.
2. DEMOC has an Effect, unlike MOBC.
(Sorry, I had no other place to put this message.)
