Treacherous Thoughts

Kicker {1}{w}{u}{b}
Look at the top three cards of target player's
library. You may cast one of those cards without
paying it's mana cost and you lose life equal to
it's converted mana cost. If this spell was kicked,
you may cast any number of those cards without
paying their mana cost and lose life equal to their
total converted mana cost. Put the rest of those
cards into their owner's library.
