BR-Threaten

[GoblinPiledriver]

A friend of mine send me this deck list. It's a semi-aggresive BR Deck with a strong stealing and sacrifice subtheme.

Any ideas or comments?

Some stuff I would consider playing (played this deck myself some time ago):
Bazaar Trader -steal your opponent's creatures permanently or give Persecutor to him/her.
Mesmeric Fiend -sac with etb-trigger in stack
Murderous Redcap -persist is your friend
Imperial Recruiter -utility
Furystoke Giant -wrath opponent's team away + persist
Recurring Nightmare -get all goodies back
Grave Pact -don't know about this. Could be decent?
