When do the "owned" cards become Spider Clan personalities? After they're in play, or any time they are in the deck? I thought that an owned card was any card in the deck after the game began. If that were the case, I would have thought that the Mask would have made Oni no Akuma a Spider Clan personality before entering play.
Just asking for a little more explanation.

"May not be negated" means it cannot be overridden.
