Banshee

{x}, {t}: Banshee deals half X damage, rounded down, to target creature or player, and half X damage, rounded up, to you.
To hear her wails in the dead of night signifies someones death tonight.
Foreboding, this harbinger of doom's message does wait at the threshold. The reaper comes and snags you,
brings you through the shadows pull. You think of how it came to be that your life, so wonderful, has come to an end. With one Banshee's call.
