This looks like a very well built and effective spellbook, Biblofilter, and the results clearly proved it.
Great job.
Some of my questions were already answered above but I am still interested to hear
1- what was the role of the lone Flameblast ?
2- You explained the inclusion of the Blood Demon already.
My first thought was he might have been added to give you an advantage in a Necro vs Necro matchup. ( Bloodthirsty getting around any Undead Guards ... )
Of course the Demon having Flying and thus be visible to your Necromancer from behind his Walls also leaves some nice tricks to be explored. ( Enchantment Transfusion )
btw great to hear you took that "2-walls-minimum" to heart
Walls are so underrated and so effective if timed well. Imo there's a moment in nearly every game where a wall is the best card to play.
3- Why 2 Magebane's and just 1 Marked for Death ?
I could see the book be even more efficient if it were the other way around.
4- Two more cards that could be really helpful for this book imo : Eagleclaw Boots and Astral Anchor.
Were there games where they tried to push/teleport you away from your defensive position and if yes, how did you solve it ?
5- Was the inclusion of a Zombie Brute an option at one point ?
Overall, nice to see MW is alive and kicking with a Necromancer, Druid, Forcemaster and Warlock in the final 4.
