Mind scan is still superior, it reveals ALL set card on your opponent's field and not only 1.
Also, this card reveals during the end phase, which is kinda pointless since most of the time you want to know your opponent's backrow during the main phase or battle phase so you don't run into one of their traps.
I think it works in your opponent's end phase too(the card does not say that olny your end phase), so you can check a card right after it set. So after you activate it youbcan check one in your end phase an one more in your opponent end phase. But yeah it still sucks xD
