Nurgle’s Grand Pestilence

(You may cast a legendary sorcery only if you control
a legendary creature or planeswalker.)
Put eight +1/+1 counters on every green and
black creature in the battlefield, and eight -1/-1
counters on all other creatures. Exile this card.
No matter how much technology progressed, how intelligent all species became, or how much they progressed, they all still would eventually keel to
sickness, one way or another.
