If an effect refers to a card or spell that was foretold, it means a card put in the exile zone as a result of the special action associated with a foretell ability, or a spell that was a foretold card before it was cast, even if it was cast for a cost other than a foretell cost

Combine it with the right vampire cards, and you're packing some serious power
