Aero Shield

As the blade flew down at the wizard, his life flashed before his eyes. He saw his father, a great scholar, kneel before him and present the first scroll he had ever drafted, polished and ready for use. Just then he remembered. His scroll was still in his pocket! As the wizard pulled out the scroll, the blade began cutting the top of his head. He gritted through the pain and sickly created a shield shape with his hand. Just soon as he cast the spell, he felt the blade being pushed to the side. He silently thanked his father as he finished off the orc in front of him. 

When you cast Aero Shield, anybody targeting you with a melee attack has a disadvantage until the start of your next turn.
