Vasha the Defender

0: You may attach or unattach target creature
you control to a mechanism you control.
When Vasha the Defender comes into play,
Venera has protection from all colors and is
indestructible. Only one Vasha the Defender
may be in play at any time.
When Vasha is dealt combat damage, target
player loses that much life.
When Vasha leaves play, shuffle Venera the
Seeker into your library.
