I understand where you're coming from. Then perhaps you can add creatures that have auto sac or discard outlets? This way you can get your creatures in the yard quickly and recur them that way. One combo i came up was running
Chainer, Nightmare Adept with my
Hell's caretaker in my
Sedris, The Traitor King EDH deck. Untap, upkeep, discard a creature you want in the yard, then tap the caretaker to sac a token (your devil token would be best), bring out your big beater for essentially free, then you can STILL cast another creature from your yard. Double the reanimation before you even draw for turn. This combo also works with
Kroxa, titan of death's hunger because you can keep recurring him for card advantage without having to pay the escape cost or
exile any cards. How does that sound?
