Sounds good, didn't realize they were on 25s, almost everything is on 32+ for my NH (so glad I painted up 20 Bladegeists...) and yes I was trying to justify something besides Petrifex, but I just don't see it. I'll probably do a custom color scheme so I can switch things around.
I ended up picking up Horreks riders, box of mortek guard, crawler, harvester, stalker/immortis box and a couple foot heroes. I already had Arkhan from the start collecting skeleton horde. Do people have any thoughts on 20 vs 30 mortek guard in a unit? Also I realize they aren't great, but could Immortis guard see some play as babysitters for some of our more fragile heroes?
