icon or button design for The Sorcerer's Apprentice (iPhone app)

The Sorcerer's Apprentice (iPhone app)

This is an companion application used while playing the Sorcerer's of the Magic Kingdom collectible card game at Walt Disney World's Magic Kingdom theme park.

My primary need is for an application icon for the iPhone (in various sizes as required by Apple for app store submission).

If you search the web for the Sorcerers of the Magic Kingdom, you can find examples of the card art, etc.

While I'm open to any design ideas, I think that a good icon design would incorporate some or all of these elements:
- A sorcerer. While Mickey Mouse as the Socerer's Apprentice in Fantasia would be the obvious look to go for, I don't want to infringe any Disney copyright. Maybe a human sorcerer but in similar garb -- red robe, blue hat with stars. Maybe even wearing Mickey Mouse ears as a tourist in the park.
- A portal. The game is played at portals throughout the park; the look is like a magic mirror (long oval). The portal might include an image of a villain to be fought, such as a dragon.
- The collectible cards. See attachment for sample images. The sorcerer holds cards up to the portal to fight the villain; a literal icon might show this happening, or might just feature certain elements.

A style suggestive of Disney animation would be appropriate, but I'm also open to other interpretations.
There is also a need for tab bar buttons and perhaps some promotional artwork that may be done as follow-on to the icon design.
