Okay, here's the scenario: I make a rescue attempt with a blue Genesis hero.My opponent blocks with a brown EC and plays Land Purchase to search his deck for a site to put his only available Lost Soul in. He is now losing. Am I able to play Numerous as the Stars to search for Levi and band him into battle (Levi's SA gives him access to any site), or does the rescue immediately become a battle challenge when my opponent puts the Lost Soul in a site? In other words, are you able to turn a BC back into a RA without using a negate?
