Sayu's Beacon

Enchant creature
Enchanted creature gets +1/+2 and has vigilance. If enchanted creature is an Assassin, it also has unavowed and first strike. (A card with unavowed doesn't trigger the abilities of permanents.)
To those who walk the path of moonlight, Rehi and Sayu became beacons of hope. Even to those who crept in the dark, Amsu's moons became symbols of a new future just on the horizon.
