Reality Scramble

Reality Scramble can target any permanent you own, including those another player controls. A token’s owner is the player who created it.

The target permanent’s last known existence on the battlefield is checked to determine its types.

In most cases, at least one card in your library (the card you put on the bottom of your library) will share a card type with the target permanent. However, in some unusual situations, no cards in your library share a card type with the permanent (perhaps because the permanent was a token or its types were changed). In that case, you’ll reveal your entire library, put nothing onto the battlefield, and put the cards back in a random order.
