I vote for team DC.
Wonder Woman is strong enough not to get punctured by the claws and would probably hurl him 'round and 'round. Wolverine can cut through a variety of things but metal and sheath and stuff like that tend to slow him down and he resorts to slash after slash. I think Wonder Woman could probably knock him unconcious fast.
Batman and Dare Devil would be a cool fight but Batman just has the upper hand here. Master tactician, escape artist, intelligence level, kaleidoscope of gadgets, etc.
Nightwing and Elektra? Well Actually I think Catwoman can beat Nightwing so yeah...Elektra would have a chance in stumping him. But it wouldn't take long for Batman or Wonder Woman to swoop in and KO her.
