Indeed i felt that FoW is not necesary as a main card. The decks wins almost every 1st game.
Last night i had a small tournament (8 bodies) and faced not 1, not 2 but 3 deathrite shaman game 1!
The deck took its time but finaly raced them.

One thing i noticed was that i always wnated chancellor x 4 each game. Even postboard. I faced BUG, Reanimator and deadguy (with leyline game 2 and 3, )

Iīm not sure if this is correct. i always cut 1 shambling, 1 return, 1 phantasmagorian, 1 proggy (if it wasnt show and tell, otheriwse i cut shadow).

My list was like echelonīs one but with chacellor instead of probes.

And side was:

4 Unmask
4 Blue trap
2 contagion
2 black shoal
3 macabre

Another thing i felt was that i wish i had Fow in the side; to be reactive.
For example, in the deadguy 2nd match i went for un mas expecting rip. When we started the game i had unmask in the opening but i hesitate aboiut playing it beacuase probably rip would not have been in my opo hand in that moment. I wandered: Is this the right moment for casting unmaask?
Just a feeling

On black shoal: the only mutch up i felt i was over contagion was when i wondered: "Could i have killed that elesh norn if i would have sideboard shoal in?"
