Fenrir Unbound cannot be countered
When Fenrir Unbound enters the battlefield,
destroy all opponents lands.
If Fenrir Unbound is in your graveyard, sacrifice
a creature to return it directly to the field

And it is said that he will swallow the moon and
defeat the gods, and the world will end and start anew
