Forum:About crush card virus

I got a question.... my friend told me that if I use crush card virus i can check his facedowns/faceups/hand for monsters that has 1500 ATK and above and destroy that... but after that beginning in his turn i could only check all the cards he draw and not the cards that he has in the field or moved to his hand... i'm just confused about this... how does crush card virus really work??

hoping someone could answer this... thanks ^^
