Not so buffet-y, the small fluff of the Iybraesil Craftworld caught my attention. For a Craftworld that is matriarchal and features Banshees, I came up with this 1850 list:
HQ:
Farseer + Singing Spear
Autarch, Banshee mask, Shard of Anaris
Troops:
Storm Guardians x10, 2x Flamers, Warlock
Guardian Defenders x20, 2x Bright Lance, Warlock + Singing Spear
Guardian Defenders x10, Scatter Laser, Warlock + Singing Spear
Elite:
Howling Banshee x10, Exarch, Executioner
-- Wave Serpent, Holo-field
Howling Banshee x10, Exarch, Executioner
-- Wave Serpent, Holo-field
Fast Attack:
Crimson Hunter Exarch
Heavy:
Fire Prism, Holo-field
Night Spinner, Holo-field
With a spare 40 points for other stuff that I don't know what to plunk them on yet. Most likely vehicle weapon upgrades and stuff.
