Summon the Wither

Create a 10/10 Black Wither creature token with
Flying, Haste, and at the beginning of each
players turn, destroy up to one other creature
that they control at random.
I want to leave a smoking crater from which
not only will Manburg never recover, but from
which no new country can rise in its place.
History will FORGET that a country
ever existed in this area.
