A recently discovered internal error will prevent the Ikoria: Lair of Behemoths Japanese-language exclusive Godzilla Series Monster cards from appearing in English and French Collector Boosters.
The alternate versions of cards numbered 385, 386, and 387 can only be found in Japanese Draft and Collector Boosters and as Japanese Box Toppers.
The cards affected are the Japanese-only versions of Mysterious Egg, Dirge Bat, and Crystalline Giant.
Wizards of the Coast (WotC) will not be able to reprint the product in a timely manner and instead will be printing and distributing copies of the cards to stores soon. The plan is for local game stores to be able to provide some number of the above cards to those who purchase English of French Collector Boosters.
