Brazen Uncaged

Devoid, Shroud, Double Strike, Lifelink
Protection from colors.
You may pay 15 life and sacrifice a human to cast
Brazen Uncaged instead of paying its mana cost.
If you do, you may search your library for a
human rogue, exiling it until Brazen Uncaged
leaves the battlefield. When Brazen leaves the
battlefield, put the Human Rogue onto the
battlefield tapped.
