yeah, 4 archers is a lot to attempt to get out! but an archers watchtower is not a bad idea!
Also, I love the graveyard especially since it can summon the wraith! But with a necro, I have found the libro to be much more efficient over the graveyard. 1 less sbp and 4 less mana. This helps you off to a good start by having the extra mana early and you can still harmonize it if you feel so inclined. Libro is also better against big buddy builds. Graveyard is excellent for enemy swarms if you can keep knocking them out and getting the extra mana on it. But the libro gives you the same function, it's mobile, and will not be affected by how many creatures your opponent has. just curious why you chose that over libro?
I also agree that the bats could be taken out for something since they cant be deployed and your main actions are so crucial.
Also, vampirism and drain life are great but are you going to use both before dropping a deathlock? or are they used in case of an early rush?
As mentioned before, teleport, force push, and tanglevines are great! espeially when you want to deal loads of damage and not have them run away. One nice thing I have found, though, is to use a force wave - I use it mainly with zombies to get them in a better position - but it would be nice here to move all of the archers 1 zone closer to the enemy with your qc so that they could all use their full actions to shoot instead of moving.
It looks good, though. I'm not a big fan of skelly necros so I always like seeing them posted on here
