Luan, the Bird

Flying
{2}{g}, {t}: Tap target creature.
Over the mountains, and over the seas
The Luan spreads its wings and weaves
Feathers that trace a path of peace
Wings that bind hearts destined to leave
And oh the Luan, its work being done
Flies alone into the darkness
Searching for the other half
That is not meant to be.
-Silsword, "Tragedy of the Luan"
