The deck is pretty funny to actually play.  If you try to keep the combo going it will eventually crash, but I think the problem is from Timetwister and not floating mana as I've had over 100 mana floated at a few different points.  Because of 16 0 drop creatures you can generally stay alive long enough to combo out your opponent.  The only problem is that the deck can randomly fizzle after you've been going off for a while, like when I used to sac all my kobolds then time twist them all back in and draw 7 kobolds and proceed to burn for 80.  I'll post some other random decks I have when I get back from the ptq 

Since I think I am one of the only people in recent memory to play a deck with Shahrazad in it I will lend some of my thoughts on it.

There are many ways to interact with Shahrazad and that card in particular can mess with an opponent's state of mind more than any others that I know of. I have had people concede sub-games to me after resolving a mere Tormod's crypt or Samurai of the Pale Curtain or Swords to Plowshares and that is generally only if the opponent knows the interactions with the card.

If the oppoenent does not know the card very well than you cause them to get flustered and worried over what might happen. The card often leads to play mistakes by my opponent that they probably would not have made other wise. Because you are playing the card you are much more likely to win a sub-game, especially if your opponents deck revolves around win processes that might remove cards from the game.

Not to mention it isn't that terrible of an early spell and many players will simply counter it because they do not want to deal with the card taking counters away from other threats more relevant to the currnet matchup. Assuming you win the sub-game and you are the aggro deck the clock is much greater than normal fish decks. I can honestly say I haven't lost many sub-games. The most restricting nature of the card is the WW casting cost which can be hard for a lot of decks to play because white is often a splash color in Vintage.

Much to the popular belief of people on the fourms, almost none of my oponnents have immediately conceded a sub-game.  In my particular case, they see I am playing White Weenie, they assusme I must be a scrub and should be able to beat me and then decide to play the sub-game out.  A very subtle interaction with the card from a sub-game is that by identifying the threats your opponent is playing, you can reasonably figure out what his main game plan/hand must consist of therefore you can mentally prepare yourself for how to play the turns immediately following the sub-game.  More often than not, it acts as a 10 point burn spell for 2.

Short story:  My opp. is at 4 life and has dominant board posistion.  I had earlier resolved Shahrazad and won the sub-game.  Since i first cast the spell my opponent has been making numerous errors and was in a complete state of mental disarray.  On my turn I cast Shahrazad, the kid then mana drains it, I then cast a second Shahrazad for the turn the kid immediately concedes since we were drawing near time taking him to 2.  I pass and Orim's chant him during the upkeep.  He simply draws a card and says go.  I point out he burns from drain mana and that I win and the kid came as close to crying/fighting me that I have ever seen from a magic player.

@desolutionist:  I'm really sorry round 2 had to end the way it did. You were a really good opponent and like you said, had you conceded the sub-game you would have definitley won the round.  In game 2 I completely miscalled your deck thinking that you were CS because of TFK and LoA so my boarding strategy went out the window and you comboed me out pretty severely.  As to the proxied chants; I'm poor that is why I play WW in vintage  ( first list of the deck came in at just under $100 ), although I did get a signed Shahrazad just before the tournament.  For the future I will try and have my proxies more readable, so I will just have someone else write them I have terrible hand wrinting. 

I was the only one playing White Weenie    but yea there was more drain than everything else put together.
