Hi mate, by all means go and enjoy yourself!
In the past few tournaments I’ve been to, I’ve seen lists of all kinds. Both well-tuned agressive lists and more casual lists. In the first game you might up meeting an opponent with multiple tournament-wins under his belt. After the first rounds these things happen to even out so game 2 and 3 are usually against opponents with more or less the same experience as yours.
Likewise, the list you choose is of lesser importance than how you play it.
With that being said, a few tips here and there. Use whatever you want and discard the rest!
You have a nice mixture of hard hitting units (werewolves, wights) and damage-absolving units such as wraiths, skeletons and zombies. Of these anvils, 3 hordes of damage-soaking infantry (skellies, 2x zombies) are maybe a bit too much. I’d drop the skeletons if you want to keep the formation.
Spoken about the formation. I’ve tried it several times and found it to be only partially effective. Phalanx upgrade on zombies isn’t that effective.(no one i his right mind wants to fight zombies anyhow, so equiping them with spears will not change this). Moreover, I prefer zombies in hordes instead of legions (because: cheap) so the formation forces me to upgrade them twice.
If I were to change the list, I’d downgrade both zombie legions to hordes and drop the formation and the skeletons. This frees up a lot of points for additional units. As the previous poster mentioned, I’d aim for at least 12-14 units.
Also, you have a lot of points up upgrades/magical items. Aside from the inspiring talisman (and maybe the pipes of terror), I’d drop everything in favour of additional units. I like ghouls, but death packs, soul reavers and revenant cavalry are all good options.
Finally, you have only two sources of inspiring. (necro plus lycanis) which is a bit on the light side in 1,995 points. If you want to go the drain life /periscope route, why not upgrade the 2nd necro to a lich king? It’s expensive, but you’ll get a more potent drain life plus inspiring on a very sturdy base.
Good luck and enjoy the game!
