Wow, thats awesome you posted about the Black Vise unrestriction... I've already tested it in both my Vintage U/W Landstill and in my casual Vintage Scepter Chant... what seems to be the problem is that most of powered Vintage seems to run at instant speed anyway so it's not as usefull as it was back in the Necropotence days.
The only thing that seemed to work was post Scepter lock, but even then it's really obvious that I took out - 2 Decree of Justice, - 1 Tinker & - 1 DCS for the + 4 Black Vise as an alternate win condition. After about 6 games I just got really frustrated and ended up putting my original deck back together and taking the 4 Black Vise out.
Here's the Scepter Chant list I ran it in.

Really, I didn't want it in the opening hand because I'd rather try to assemble the Scepter/Chant lock, but dropping that 1st turn is pretty hilarious (and always unexpected). I just feel that Vintage is much too fast for Black Vise.
Of course there will probably be some sort of BrokenVise.dec to pop out over the net directly after this post.

EDIT* Btw, I know that playing Scepter Chant in Vintage is mostly suicide... it is however currently my favorite deck
