ok well i have also been thinking about taking on a 3rd project this summer.. one being windrider eldar, another being a necron tomb guard. the 3rd could, quite possibly, be a kroot mercenary army. Here is a 1500 point list for you guys to sink your teeth into.
Master Shaper 5 eviscerator attacks on the charge, 4+ invuln, wings, re-roll first turn
3 shapers S4, power weapons, melta guns, wings
20 carnivores, shaper, eviscerator, blood of the stalker (infiltrate d6" closer)
10 carnivores, shaper, eviscerator, blood of the stalker
11 vultures, shaper, frags, pistol, eviscerator (all have wings, infiltrate)
11 hounds
10 kroot, shaper, frags, fleet, blood of the stalker, eviscerator, surefoot charm (2 dice pick highest for fleet)
12 hunters (snipers), shaper, storm bolter, power weapon, auspex
12 headhunters, shaper, frags, fleet, blood of the stalker, eviscerator, surefoot charm (2 dice pick highest for fleet)
the headhunters can choose to make 1 attack a piece that wounds anything on 4+.. for high T guys.
1500 pts.. 90 models give or take with the changes
all at either +1 initiative or 6+ cover even when not in cover
so this list looks just fun as hell. could probably build it for around 250 bucks all brand new stuff. honestly it would just be for fun, though it can be extremely competitive. whoever wins, the battles are quick!
