Why are cards from “illegal” editions allowed, e.g. Collectors Edition and Championship-Decks?
We wish to make this format available and accessible for as many persons as possible without being too restricted by the wallet. Here care must be taken that the played cards from such editions not differ from the back side from “normal” cards e.g. using opaque card shields or rounding the corners of I.E. or C.E. cards. This preserves the availability of the format for beginners without restricting the card pool.
