I don't have an orc figure on my page GP. It might be a directed ad or something on the website showing us different stuff.
I like the look of the box set. I havn't got any necrons, but I've been planning to start Ad Mech for a while and turn my guard into a combined Imperial Army. I like the two little baby knights. I'm surprised by what looks like a power disparity in the forces. They mention at one point that each baby knight is a super heavy slot, but the necrons don't look like their geared up to take down super heavies. Maybe it relies on scenarios, or the knights are a bit towards the weaker end.
