Rate my Pokemon Black Team Please?

Give Zoroark Flamethrower and Focus Blast over Hone Claws and Night Slash, he shouldn't be using physical moves. Replace Emboar with Darmanitan, his moveset is stronger and more diverse. I would have to scramble your team completely when it comes to competitive battling, especially removing Reshiram, unless you would like to play in the ubers tier (pretty much mostly composed of legendaries.) You would also have to learn about Effort Values, natures and what-not.
