Braden, World Walking Expert

You may exert Braden when it becomes tapped.

If Braden is attacking and exerted, it gets +2/+0 and indestructible until end of turn.

{t}, sacrifice a nontoken permanent: reveal cards from the top of your library until you reveal a card that has a mana value equal to or less than 1 + that of the sacrificed permanent and shares a type with it. Put it onto the battlefield. If Braden is exerted, you may search your library for that card instead.
