Great spellbook you have there! I find it very balanced. You seem to have covered most of the big threats: walls against a fast/hurlboulder opening; Maim Wings against flying creatures; Ravenous Ghoul, Flaming Hellion and the Ichthellids against NonLiving (although, you can't impragnated non-living creatures); enough Acid Balls to take care of most armours; Grey Wraith against the Incorporeal conjurations or creatures. Am I missing something important?
Remember, Acolyte and flaming Hellion cannot be summoned from Graveyard. Not a big deal, as long as you keep it in mind.
You seem to favor the zombie swarm strategy. What's your opening? I'm guessing Graveyard + Death Ring. You probably want to get Sacrificial Altar and then Ziggurat soon after that if you want to get the most out of them.
Some minor tweaks I suggest:
- 4 Walls seem too much. Do you really need them all? I think 2 would be enough.
- I don't know what meta you're playing with, but do you need Mana Prism? That's 4 spell points.
- Nothing for Finite life? What about Deathlock or Poisoned blood? These can take you a long way against Druids.
- Personnally, I always keep an [mwcard=MW1J11]Idol of Pestilence[/mwcard] with my Necromancer, that's one easy Poison Damage per upkeep and doesn't alarm the Opponents much usually. Under pressure, they will usually not go for the Idol and will take the damage. But, again, that's a personal preference.
Finally, since about 66% of your creatures cost less than 10 mana, I would advise against a meditation amulet. Just replace it with a Mana Crystal: same amount of spellbook points, but doesn't take your actions to use it.
Beside that, I guess all you want to do is keep coming those undead creatures of yours. Don't let the opponent breath!
Good game!
