Hello again !!
I) Psychic war
The new nids are really bent on ruining Psykers day !
Combined with with shadow in the warp it's interesting !
II) Weird combo.
Yea on the paper it's strong getting T8 and -1D to all attacks. But you don't control the activation.
III) Bio artifacts
(Good to have confirmation, some spoils had error)
This venom canon is tasty for sure !!
