In December 1993, Wizards of the Coast released a boxed set containing each card from the Beta print run. This set was called Collectors' Edition.
The set is augmented with duplicates of many land cards, making a total of 363 cards.
With Collectors' Edition the concept of artist proofs was introduced.
International Collectors' Edition is a second print run of Collectors' Edition with identical content.
All these cards are printed on an alternate paper, they look as modern as those from 1996.
