You have to go through every stage (first opponent is pegasus).
To get Dark Magician, you have to gain access to the fourth area or higher. Grandpa will say he has some new capsules, so check it out. It will be in the dark section of the capsule shop, near the top. It may take a little while, but worth it for an A-ranked capsule.
