Lurrus, Hunting Nightmare

Lifelink
During each of your turns, you may cast a spell
with mana value 2 or less from your graveyard as
long as you've cast only one other spell this turn.
If a permanent spell would be cast this way, put
a finality counter on it when it enters the
battlefield. Otherwise, exile it as it resolves.
When a pleasant dream becomes hungry for fear.
