If you get a global Mystical Archive card in your Collector Booster, it means that your foil-etched rare or mythic rare was the Japanese alternate-art version (and vice versa)
Perhaps the biggest surprise with this card is that it continues to bounce up and down in value, from as low as three dollars to as high as roughly $5.50
however, these two cards provide examples of the two ways Wizards is mostly like to "miss" and end up with a card that is broken enough to be banned in Standard, in the current day and age
There are many ways in UW to pop off with this (tapping and untapping, for instance), but you dont really even need them to enjoy the value that Shorikai brings
