Hey, anyone else seen this loophole yet?
INQUISITORIAL DETACHMENT:
HQ - Genestealer Hybrid Magus (counts as Inquisitor Coteaz)
HQ - Genestealer Patriarch on Throne (converted with dreadnought legs so it can move) (counts as Krazypants)
Elite - 6 Purestrain Genestealers (count as Arco-Flagellants), 6 third generation Genestealer Hybrids (count as Acolytes)
Elite - 6 Purestrain Genestealers (count as Arco-Flagellants), 6 third generation Genestealer Hybrids (count as Acolytes)
Elite - 8 third generation Genestealer Hybrids (count as Acolytes, with a couple of the heavier weapon users counting as Servitors), 2 fourth Generation Hybrids (count as Psykers), 2 first Generation Hybrids (count as Death Cult Assassins)
Carapace armour to all the Acolytes, plus the usual random assortment of Genestealer hybrid weapons (all legal, Acolytes can take a pretty broad range when you add the three specials per squad).
Dedicated Transport 1 - weird limo/APC type thing (counts as a Rhino)
Dedicated Transport 2 - weird limo/APC type thing with better weapons (counts as a Chimera)
Dedicated Transport 3 - weird limo/APC type thing with Heavy Bolters glued on (counts as a Razorback)
Swap out "Coteaz" for a generic Inquisitor if you want to take the three baby Genestealer models to count as Servo Skulls (d'awwwwwe!).
Ally with an Imperial Guard army. Congratulatons, you now have a legal Genestealer Cult army (like the one in my gallery).
