For those of you who don't know what it does:Negate the activation of a spell, trap, or monster effect that targets a DARK monster and destroy it.
I'm thinking that this is an awesome card for decks like Blackwings and Gravekeeper's, who don't have protection as far as I know. Also, it could be sided AGAINST decks such as those, to stop annoying cards like Kalut, Sirrocco, and I believe even Black Whirlwind(needs rulling). What do you guys think?
P.S. I am pretty sure that this article goes in TCG Discussion, but forgive me if it doesn't.
