I played this deck aswell with little bit changes.
i went 2-2-1 after that i dropped cuz i knew i couldn't go T8
My first matchup was against a random elf deck.
This was an easy win with dreadnought and second time with grindstone.
Second match up against a tendrills deck.
first game i drop turn 1 dreadnought but he bounces with chain of vapor.
then i hold control with mystic remora for 3 turns, i stopped paying for my mystic remora and dropped painter and grindstone.
just needed 1 turn more and i hade a counter back up, in his turn he duressed me and won.
second game i lost cuz i had a mana screw. with the help of top brainstorm recall and ponder i didnt found my third mana source and lost.
third match versus world gorgerdragon
this was an easy win with first turn magus to kill his bazaar and other land he had in play.
i saw he was playing dragon deck so i boarded some tormod's crypt in.
with main 4 stifle's it was an easy game specialy cuz i saw 3 of them.
against slaver i had a draw.
not really interesting game went more like draw go draw go, i noticed that sensei top is really making the game slow.
I forgot the other game i lost maybe i'm traumatized :S

I changed 4x thirst for knowledge to 2 sensei top and 3 portent, These work kinda nice together cuz you can look top 3 with portent shuffle if needed and look again with top.
also you can get 1 of the 3 cards you saw with portent and draw it with top if needed.
and in the next upkeep draw your top again.
i would change the card draw enginge cuz i dislike top in vintage (its making the game very slow).
Thirst for knowledge is 3 mana cost and you really want to play trinket mage or magus for this mana, but maybe i try it out some more.
Sideboard was kinda solid.
it was nice to take my opponent's DSC and beat him with it

.
rack and ruin, and ingot chewer was not needed but still i didnt saw much of stax or chalice, null rod decks
