About Marvel Vision (Base Set)
The cards are raised to give depth. The set is divided into 4 sections: Spider-Man, X-Men, Fantastic Four, and Iron Man. All cards (except the checklist) contain a trivia question, with each section naming the trivia question a different thing ("Web Zinger", "eXam", "FOR Your inFORmation" and "Mental Metal Test"), and the trivia question answer is printed on each card, but obscured by red type. The "Encryptalyzer" card has a red film panel which makes the trivia answer apparent, but the card is not needed if you look hard enough.
The 4 Card set of "Mini-Magazines" is also quite often included as part of the base set, along with the "Encryptalyzer", due to abundance of those inserts.
