Again, thank you for the very in depth reply!
I was just about to ask about chalice's before I refreshed the page and saw that The Chosen One had allready adressed this question. To follow up on this issue, I assume that the spell snares are being used to counter the scrolls, or more importantly the flashes so that they cannot flash in hulk. I would deduce that this means that you have forgone chalice'ing their summoners pact so as to have more spell hate potential versus the true killers? Is this corret?
Overall I will just have to playtest the crap out of this as soon as I get a chance. I love the list as a whole, and I understand that the sideboard really is a bit amorphous unitl the meta is established, I will have to scrutinize over what has been played over the past few tournaments to really make final decisions (which I am sure I will change day of

)
Once I have played it a bit more, especially versus true vintage arch decks, I will have a better feel

@Dave and Chosen One:
Sideboard versus Goblins? I am a bit scared of this which went 2nd at the last eudemonia:

Solid man thank you, I will try to get out to eudemonia and see if I can get some games in. Sorry to hear your local shop was closed, Vacaville is a bit of a drive. I should know since my GF lived in Davis for 2 years
