Forum:Clay Charge vs Gravekeeper's Visionary

I had Gravekeeper's Visionary out on the field in attack position during my battle phase with a Gravekeeper's Spy in my hand. I also had 800 life points left. My opponent had a Elemental Hero Clayman facedown in defense position as well as Clay Charge facedown. I attacked Clayman with Visionary and my opponent activated Clay Charge. In response I discarded Spy using Visionary's effect to prevent Visionary from being destroyed.

Does Clay Charge still revolve if Visionary isn't destroyed? Basically does Clayman get destroyed and do I lose the 800 life points?
