Interrogate

Choose one creature you control.
Interrogation deals 1 damage to that creature. Look at the top card of your library. You may put it into your hand or onto the bottom of your library.
If you put the card on the bottom of your library and the chosen creature's toughness is not 0, you may repeat the process.
