anything that has shaggoth eating zombie minions early and every turn is going to be a good build
Meditation amulet works great with the Necro- it just does.
The thing I like most about the necro is with just one build- you can deside to
A. Stay back and summon hoards of creatures
or
B. Go for the throat and keep on the presser.
Other builds can do this sure- but with the Necro its just so fluid using the same build. He is scary if he is aggro- and IMO he is REALLY scary if he has hoards that just rush and surround you late game.
And yeah- this looks like a great opening. For me personally- I stick with only one spawn point and dont often use two on the board at the same time. But I know a few that do, and it works for them.
I also prefer to get out Shaggoth as soon as possible, then have my spawnpoint summon a minion, and have shaggoth devour it ASAP. That leaves my Necro open to cast counters,conjurations,attack spells,ect.
Nicely done OP.
