Surely with over 200 zombies the wood elves wont have the upper hand, if they out manouver you then you can raise a unit purly to meet them untill support- flanking zombies or even a vampire with a skeleton unit. Dryads admitingly are pure filth ( i used to play a Dryad army) but with so much magic you may get a gaze of naggesh which only requires 3 power dice, or 2 dice and a skull staff .
Maybe 9 zombie units to start was a little extreme, you could loose 3 and free up 240 pts, that can get you a vargulf- high mobility will cut down WE advantage and its hard.
If you loose 4 units you can get 2 vargulfs- now there is a team.
Just 5 Zombie units to make your horde with enough magical support might be enough as they do what zombies do best, hold something up untill Vampires, wights or Ethereals get to them.
The problem isn't that the WE might be able to avoid them, it is that they will cut them down. WE are exactly what I was talking about when I mentioned more elite troops. The forest spirit army is immune to psych so doesn't care a fig about fear and terror, and they will cut down so many zombies that you will lose every combat no matter how many zombies you have. Then you start crumbling.
In a case like this even your supporting units might be in trouble. The zombies get culled so badly that you lose the combat by 3 (or maybe more) then your special units will start crumbling (every unit will lose 3 wounds).
I'm not saying it isn't possible to win. But you are putting yourself at a big disadvantage.
Write up a legal zombie
horde list. Look at its strengths and weaknesses. and do a bit of math on how easy it is to kill zombies vs how quickly you can raise them. and look at how many supporting units you have for your army, how hard would it be to kill them, and force you to rely on WS1, S2 and T2 for the rest of the match?
Throw in some senarios like Vs dwarfs. A couple of units of xbows, an OG a GT maybe?
What if they shoot up your support units? You can't have many considering 5 units of zombies, + very expensive characters (which you are relying on to keep your army alive).
Then consider failed raise attempts and dispells. Then consider that it's usually a good idea to use your PD for more than just keeping your army together.
Then consider that you still have to fight elite troops, with a myriad of anti fear banners and CR options....
Now consider that your main tactical idea, summoning zombies to slow them until your suppot arrives, is also available to a non-zombie
horde army.
