Stolen Strategy [Fallout]

Set: Fallout Type: Enchantment Rarity: Rare Cost: {4}{R} At the beginning of your upkeep, exile the top card of each opponent's library. Until end of turn, you may cast spells from among those exiled cards, and you may spend mana as though it were mana of any color to cast those spells. “Hacking is just good science!”
