Holy crap I was just thinking about this!
I think Batman and Catwoman take this. Batman is the smartest and would probably take on Dare Devil no problem.. Heightened senses and some rods aren't going to be enough to take on Bruce.. Selina Kyle would fair up alright against Elektra and has a good chance of winning. If she can use the whip and get those knives out of Elektra's hands then its over. Most likely it'll be Batman doing the work though. Catwoman will stall Elektra
