Ovirau, Fate's "Hero"

Heroic — Whenever you cast a spell that targets Ovirau, mill X cards where X is a number of your choice between one and ten.
At the beginning of each endstep, if you
descended this turn, destroy target creature an opponent controls. They create a blood token.
"Ovirau ended the pain, suffering, and the tyranny in
a single blow. Why would he do that when in the past
those were the very things he caused?"
