this card is badConsidering if this is good for the deck:
It costs 2 and unlike Scry>1 effects it only lets you manipulate exactly the card at the top, meaning that you have to use it the same turn as a cascade card. So, you need 7 mana for dropping a extra 2/1 and improving your Noise Marine hit and at that point, is it really helping that much?
EDIT: if you look at constructed "cascade" decks, you're either cheating out a suspend card via cascade or (more relevant to this discussion) you are just running a solid midrange deck with lots of cards that are good to cascade into. like Boomer Jund or Pauper Cascade. so library manipulation is not strictly needed for cascade to be good. just good cards to cascade into.
