Forum:Crimson Nova the Dark Cubic Lord to Necro Gardna

What happens? Necro Gardna has less than 3k attack. okay. But my friend argues that it stops the next attack so Crimson Nova the Dark Cubic Lord is still affected.

So basically, if you don't understand. On my turn he uses Necro Gardna. When I declare attack the same turn with my Crimson Nova the Dark Cubic Lord am I affected or not? Basically what happened. I happened to have no other monsters I can get out.
