Hide

Hide is a keyword action featured on the Unstable card Entirely Normal Armchair. It means to put or keep a card out of sight on the battlefield.

Rulings

 * The card must be in your hand for you to hide it on the battlefield. You can't sneak it onto the battlefield from outside the game or from your library or from anywhere else.
 * It doesn't have to be behind another card or item on the battlefield. In other words, you can hide it in plain sight. Easier to spot there though.
