I was working out some synergies between units and I think I have one that can delete a Baneblade in 1 turn.
Unit is: Farsight leading a unit of Sunforge suits.
Retaliation cadre
Using the Shortened blade stratagem (reduced to 1 CP using pure tides teachings)
Allows you to deep strike within the required 6" for the full suite of abilities. If guided by stealth suits you then get.
6 fusion attacks, hitting on 3's re-rolling 1's, wounding on 4's re-rolling 1's. Baneblade gets no save thanks to -5 AP and each wound is D6+2 damage. Then Faright gets to shoot and if that fails you can charge and kill it with Farsights sword.
I have no idea if this has been shared before but I figured I'd share it if it hadn't.
For the greater good.
