Theoden, King of Rohan

Whenever Theoden, King of Rohan or another
Human enters the battlefield under your control,
target creature gains double strike until the end
of the turn.

"Arise, arise, riders of Rohan!
Fell deeds awake, fire and slaughter!
Spear shall be shaken, shield be splintered!
A sword-day, a red day, ere the sun rises!
Ride now, ride now, ride to Gondor!"
