I use old incubi and mandrakes, i use the old beastmaster as my bloodglaive succubus and i have that haemonculus with a liquifier. I do have the old wyches, but i dont use them. However i kitbashed hydra knives and just use the hydra gauntlet rules for them. I have an old jetbike i used to run as a dracon on jetbike. He rolls with a bunch of new jetbikes and like every chaos player gets jealous of the spikes.
