Atraxa, Martyr of Mirrodin

Flash, Flying, Deathtouch, Vigilance
When Atraxa enters the battlefield, creatures you control gain indestructible until end of turn. If creatures you control already have indestructible,
they also gain lifelink.
Atraxa singlehandedly protected a Mirrodin retreat
before being captured and twisted by the Phyrexians
into the glorious form she takes now.
