Total: 1749pts, 7 CP
Deployment: 2x5 Dark Reapers, Farseer, and Warlock load up in Wave Serpent for alpha strike mitigation. Autarch can infiltrate if necessary, along with 2x5 Rangers. The Swooping Hawks can deploy in the skies, and the War Walker can outflank. That leaves a minimum ground force of 10 Dire Avengers, 2 Fire Prisms, the Crimson Hunter, and the Wave Serpent.
Turn 1: Dark Reapers disembark. The Farseer and Warlock can either stay inside the Wave Serpent, and be joined by the Dire Avengers to lend anti-infantry fire support to Swooping Hawks, or they can cover a backfield objective.
Key Stratagems:
Forewarned – this may well be key with Dark Reapers and Fire Prisms to protect squishies in the backfield.
Linked Fire – self-explanatory.
Lightning-fast Reactions – great for protecting essential elements, especially as it is in reaction during opponent's turn.
Fire and Fade – I can see this being quite useful.
Changes: I'd love to add a unit of Striking Scorpions, and possibly another War Walker, but I think that would require dropping the Dire Avengers, which I'm not sure is a good idea.
Advice and feedback are appreciated, thanks!
