Himeko's Sacrifice

If a creature you control would die, it gains Indestructible until end of turn. Sacrifice a
creature you control. If you sacrificed a legendary creature, gain 4 life.
After the entire plane's memory of what had happened
was erased, Murata Himeko gave her life to save her student Kiana Kaslana from the grips of the
Herrscher of the Void. She is missed by her students
and friends every single day.
