Please, use logic and reasoning in your posts. No prep time at all, the battle takes place in New York city rooftops or streets or whatever. The TMNT have their weapons, as does Elektra, and Silver Sable has no guns, but her chakra and general melee weapons.
Who takes it?
I personally think the TMNT (due to the fact that they regularly take on ridiculous opponents and win only with teamwork and weapons), but I'm sure a counter-argument could be made for the other team.
And just to clear up......
.....the TMNT (just in case there was something else that fitted that acronym).
