Nethroi, apex of death seems like an obvious choice for creature reanimation. You can also try Anikthea, hand of Erebos for enchantment reanimation, which can get pretty staxy.

I had a nice Kathril Aspect Warper deck. It was mainly a voltron deck but used the graveyard instead of auras/equipments etc… My goal was to pack the deck with creatures that had as many keywords as possible on them and find a way to discard them reliably. I could then cast Kathril as a flying first strike double strike trample vigilance lifelink indestructible reach deathtouch hexproof menace with +11/+11 counters. Game was over in max three turns after that. Before the appearance of Farewell, it never ever got removed. I got there using graveyard tutor effects like Fauna Shaman or Jarad’s orders to get some of the most loaded creatures I could find. MVPS were Zetalpa Primal Dawn, Bassara Tower archer and Akroma vision of Ixidor (angel!). The deck is white so it’s a good idea to run some good ole Rule of law, Ghostly Prison, Thalia etc…since you might be opened a bit during early game. I didn’t really bother as I would rather focus but I did try this strat to great effect. Anyway kinda fun deck although a bit repetitive with the tutor targets and all but definitely a unique take on voltron as far as I can tell.

Maybe consider Myrkul, Lord of Bones. It can reanimate hate bears and use a token doubler on them if you’re feeling extra mean.

Look out for the new commander masters decl releasing in August. One of them is an abzan enchantment creature reanimator deck that I think will prove very promising.
