OK, Since day one of the codex I have wanted to try this. I finally got my chance. Archon with Ago,wwp,Shadow,Soul trap. With a hemonculos stock, 12 Reavers with 2 blast,2 heats, and 4 caltrops. I went against my bros Blood Angels. So the game is pretty even until I dropped these guys on his side. I thought it would pull some fire off of my normal line but he attacked it with his WHOLE army.
So this little bubble of mine was shot at by a Stormraven, Dante with a squad of Sanguinary Guard, 2 Tac squads 10 man each, A death company squad and 2 Assualt squad. Jink with FNB and some lucky rolls i only lost 3 non armed bikes in shooting. He assaulted with his DC and the 2 Assault squads. I took some nasty hits leaving only 2 caltrop bikes and my Archon left. DC had red thirst and the Sanguinary banner, they had like 60 attacks.
Using hit and run I jumped out and then rammed his sanguinary guard with Dante. I actually killed Dante and 4 of the Guard before I ended up failing a leadership with my Archon and then getting overrun. The moral of the story is, While his whole army was going after the Slay The Warlord "he had 2 cards for it" The rest of my army moved up and unloaded on any squad of his that was not in CC. He was tabled by round 4. He only had his Stormraven alive to make it to RD 4 and it was stunned and immobilized.
I would suggest trying this out its a lot of fun. If the enemy does not put a lot of firepower into it they are going to be in pain when it starts attacking.
