Enchantment - (uncommon)
When Ominous Roost enters the battlefield or whenever you cast a spell from your graveyard, create a 1/1 blue Bird creature token with flying and "This creature can block only creatures with flying."
"One raven is a bad omen. Two are a curse. I don't know what this is, but it can't be good."
—Verna, priest of Sigarda
