Invocation of Doom

(You may cast a legendary sorcery only if you
control a legendary creature or planeswalker.)
Put X +1/+1 counters on target creature where X is
equal to the number of branded creatures on the battlefield, then exile another target creature with
lesser toughness.

"It must be someone important to you, part of your
soul... Someone so close to you that it's almost like
tearing out your own arm."
