8/10 to team Marvel
Captain America is equal to Batman, and Captain America has taken down Daredevil before--no question Bats can also bring he Man Without Fear down--but I still think team marvel wins this one.
Bats will beat Daredevil but I think it would be a decently long and hard fight.
On the other hand, Elektra can easily beat Damien--and Elektra isn't the type of fighter who arrogantly underestimates her opponents. She will go all out like the cold blooded assassin she is, and she will annihilate Damien pretty quickly imho.
So the real question is: Can a weakened Daredevil and a healthy Elektra beat an enraged Bruce? I think the answer has to be a clear yes, based on Daredevil and Elektra's supreme agility and teamwork. Bats wont go down easily, but he wont use a killing blow, and with killing he has no way to win this one.
Sorry Batman: you don't always win
