And here's our answer for all those pesky hexproof creatures. Suddenly, Invisible Stalker has a lot more to concern him than the vampires' sense of smell and those freezing Nephalian nights. GoST decks will also dread this.
Like Pithing Needle , this will see a lot of use as a sideboard card. Whereas Needle would see the most use in a control deck, especially any combination of WUB, I expect Glaring Spotlight to be a favorite of burn and removal decks, particularly BR. And as my brother pointed out, Pit Fight just became a much more fun card.
This seems like a decent sideboard card, I doubt that you can mainboard it though. Also, INCREDIBLY narrow. How much artifact hate is there in standard now also?
