MTG Salvation

I'm building a lilliana death mage deck that focus's sacrificing. There's a lot of combos but it mainly focus's dictate of erebos and god-eternal bontu which allows me to sacrifice creatures on summon to draw cards. I'm in need of some Mono black mass token generators. I use quest for gravelord and dark immitations currently but I need more. Price or Mana isn't necessarily an issue but hopefully nothing to extreme plz
