The Pandorica Opens

Return all cards from exile and put them onto the battlefield under you control, all enchantments lose shroud and The Crack In Time gets exiled if it is on the battlefield
This can't be countered
So all the cracks in time will close. But he will be on the wrong side. Trapped in the Neverspace, the void between
the worlds. All memory of him will be purged from the Universe. He will never have been born- River Song
