Forum:Hero Blast vs Necrovalley

Hero Blast Select 1 "Elemental Hero" Normal Monster from your Graveyard and add it to your hand. Then, destroy 1 face-up monster your opponent controls with ATK equal to or less than the selected monster's ATK.

If Necrovalley is face-up and active on the field can a player activate Hero Blast to destroy his opponents face-up monster? I say no, but I need a second opinion.
