You had a void dragon?
Not an official Forge World one, but the I brought a second 'saucer' model to the game to which I'd attached two pulse lasers. I think it would pass for a void dragon well enough.
But I didn't want to follow Rob with a second all super heavy army. I figured I'd best put down some semblance of an ordinary army capable of defending a deployment zone, rather than my original force dedicated entirely to stopping super heavies. Luck of the draw, I guessed wrong. I ended up with four stompas coming up my front.
