Sunlight Blade

Enchant target creature.
Enchanted creature gets +2/+0 and has first
strike. If an opponent controls a dragon creature, enchanted creature has double strike.
The power of sunlight, manifested as lightning, is very
effective against dragons. When Gwyn's eldest son
was stripped of his deific status, he left this miracle
on his father's coffin, perhaps as a final farewell.
