To add my .02 worth...
These points have been mostly hit already, but to reiterate, the cards look cool, due to them all having black borders. A few multilingual folks use the cards as language lessons and translation tests.
It can be easier to get Asian cards than you might think, at least for those of you with friends/family in the US Army who are stationed in Korea. There are numerous shops outside the Army bases that sell cards in Hangul and occasionally other languages. Ask your buddy to get you some.
If your buddy doesn't know where to start, send him to the local USO on a Saturday and watch for the gamers. I suspect the Airbases in Japan run the same way.
Personally, I avoid cards I can't read, even if I know what it does (this prevents any confusion amongst friends). This results in my owning a few German (Neiderschatten und Reisenspinne sind cool). cards and the rest English.
Enjoy.
