I'm an experienced and competetive player and enjoy many a tournament, but I won't bow down to false internet wisdom and build a list that everyone else uses because it's the "most efficient list in the universe and the Codex can't beat it", as I just don't believe in such a thing.
However, I appreciate constructive criticism and well reasoned opinions, so here is my list for discussion from the learned people here:
HQ
Nemesor Onuris, master of war and destruction
Destroyer Lord - Warscythe, Mindshackle Scarabs and Sempiternal Weave.
TROOPS
Warriors - x12
Warriors - x12
Immortals - x7
FAST ATTACK
Wraiths - x5, 3x Whip Coils
Heavy Destroyers - x3
Heavy Destroyers - x3
HEAVY SUPPORT
Annhilation Barge
Annhilation Barge
Now I actually have 164pts spare and was leaning towards a 2nd Destroyer Lord (Vargard-exectutioner to Onuris) to exasperate my opponent's problems with the Wraits.
Alternatives could be a pair of Particle Shredder Spyders or a Triarch Stalker.
Opinions, observations and disagreement cheerfully awaited!
