To be honest, weakened Seraph Cas can easily defeat Dean. He could only knock him out with touching to his forehead. In super-strenght, he could't even grab Dean well. When Dean was a demon and Cas was a normal angel, he hold him off but Seraph Cas couldn't hold Dean with the Mark's enchance. (As we see in The Hunter Games, the Mark doesn't need The Blade to be activated)

Dude also Castiel gained much strenght after he became a Seraph. Look at 11x02. Hannah gets easily hurt by normal attacks, Cas didn't even affected even though he was wounded by angel blades. Also he could easily overpower angels.
