Skellies focused army but...

Hi everyone, so I haven't even played a single Game of Age of Sigmar or any kind of miniature Game, but I already painted many AOS models. So I recently finished painting the SBGL vanguard box, a Necromancer, a wight King and 20 aditional skellies, so right now I have:

1 Vampire Lord, 1 Necromancer 1 Wight King 40 Deathrattle 3 Vargheist 5 Blood Knights

I really like Skeletons but I want to wait for a grave guard/black Knights refresh, so What can I add to my army? I kinda like Dire Wolves and Lady Annika's models but I don't know where to go from here, Thanks!
