Kairi's Necromancy

Return target creature card from your graveyard
to the battlefield. It gains reach.
Flashback—Sacrifice three creatures.
(You may cast this card from the graveyard for its flashback cost. Then, exile it.)
Kairi Sisigou is noted to be an abnormality who uses
body parts as weapons themselves, using cursed fingers as bullets and turning magi hearts into grenades.
