Here's an odd one:

Kelda's [A-Level] Junk

Braxas - 210
Fen Hydra - 330
Kelda - 410
Krav - 510
8 Hexes

At 600 - Add Raelin
At 620 - Add Raelin and Marcu, or maybe Airborne Elite?
At 640 - Raelin and Marro Warriors, perhaps another Hydra?

OMs would seem tricky, but you lead out with Braxas if your opponent is squad heavy, or Krav if they are range heavy. Kelda is there for the Hydra as a mean clean up, but certainly can cover the 8 life Braxas as well if needed.
