my brother ordered some pretty cool sleeves from japan (why do they get all the cool stuff?) and tried to sleeve his 50 carder before the tournament started last season at nc regionals. unfortunately he didnt know they were yugioh sized, and and it didnt work out too well...we gave up sleeving about an hour in, and that was with three of us sleeving. they are a very, very, very tight fit (and in some cases with a slight piece of the top of the redemption card sticking out) and i wouldnt recommend it unless you had lots of time on your hands.
