I found one 6 MSU ranger brigade with banshees, hawks, fire prisms and reapers that someond made.
Any other type that would be competitive?
In addition to TheWarmaster40k and DakkaDakka, I posted that list
here too. I'll see what else I can come up with.
Keep in mind that he smallest Craftworlds Brigade looks like this, so if you just need a pile of CPs in a 2000pts game, you'll still have 1004pts left to spend on units that can use them effectively. The absolute minimum is 996pts.
3 Warlocks
6 x 8 Storm Guardians
3 x 5 Howling Banshees
3 x 5 Swooping Hawks
3 Support Weapons w/Shadow Weavers
Realistically, though, if you were going for a fairly minimalist Brigade as a base, you might as well go for min(max)imalist instead.
BIEL-TAN BRIGADE
Asurmen
2 Spiritseers
6 x 5 Dire Avengers w/Exarch, 2 Avenger Shuriken Catapults
3 x 5 Howling Banshees w/Exarch, Executioner
3 x 5 Swooping Hawks w/Exarch, Hawk's Talon
3 x 3 Dark Reapers w/Exarch, Tempest Launcher
1315pts
With the remaining 685pts, you could either add more detachments to fix the lack of dedicated anti-tank, or just add to this one. Since most of this list can move as a blob to get Asurmen's buff, if you wanted to go that route you could make the attribute Ulthwe and swap a Spiritseer for an Autarch to get a broader re-roll 1s buff. The Ulthwe Autarch can potentially get even more CP with Fate Reader.
Swapping out a Spiritseer for a Farseer and filling out 2 Dark Reaper squads might work, with or without the switch to Ulthwe. It all depends on whether you want the extra full re-rolls (assuming the Farseer takes Guide and Natural Leader) instead of the 6+++ on everything.
If you wanted to keep the Biel-Tan Brigade mostly as-is, you could add some aircraft and some deep strike screening:
2 x 5 Rangers added to the Brigade
120pts
ALAITOC AIR WING
2 x Crimson Hunter Exarch w/2 Bright Lances
Hemlock Wraithfighter
560pts
1CP
If you wanted to take advantage of the Novalance and Warriors of the Raging Winds, you could add some Saim-Hann:
(Again) add 2 x 5 Rangers to the Brigade
120pts
SAIM-HANN OUTRIDER
Autach Skyrunner w/Laser Lance (Novalance of Saim-Hann), Reaper Launcher, Banshee Mask
9 Shining Spears w/Exarch, Star Lance
Vyper w/Bright Lance
Vyper w/Bright Lance
561pts
1CP
Note that the Vypers have Twin Shuriken Catapults. Despite having Bright Lances, you would be moving them up the field and trying to charge them into shooting units by turn 2 at the latest. The Bright Lances let them soften up large models from afar while their Catapults shoot whatever's nearby.
If you decided to simply add to the Biel-Tan Brigade, you could reconfigure and mechanize your more fragile elements, like this:
BIEL-TAN BRIGADE
Asurmen (Warlord; no trait, but tough)
Spiritseer w/Protect/Jinx
Spiritseer w/Quicken/Restrain
6 x 5 Dire Avengers w/Exarch, 2 Avenger Shuriken Catapults
2 x 5 Fire Dragons w/Exarch, Firepike
2 x 6 Howling Banshees w/Exarch, Executioner
3 x 5 Swooping Hawks w/Exarch, Hawk's Talon
3 x 4 Dark Reapers w/Exarch, Tempest Launcher
2 Wave Serpents w/Twin Shuriken Cannon, Twin Shuriken Catapult
1 Wave Serpent w/Twin Shuriken Cannon,Twin Shuriken Catapult, Spirit Stones
1997pts
12CP
With two of the Serpents each carrying 6 Banshees, 5 Dragons, and a Spiritseer, the Asurmen/Avenger blob becomes easier to maneuver. The Firepikes were the last thing I added, but they could make it easier to get extra melta damage or split fire to a more distant target. Like the Vypers in the Outrider detachment above, these Wave Serpents are meant to bully shooting units, so the Twin Shuriken Catapults are fine. The Reapers get the Serpent with the Spirit Stones.
I've probably rambled more than enough for now, but I hope I at least showed that Aeldari Brigades are a reasonable possibility at 2000pts.
