Renewing Demons

[Malwing]

I came up with this deck after trying to use Deathrender and Bloodspeaker to cheat demons into play.

I'm trying to get more Demons into the deck and keep the repeatable reanimating theme.

Artifacts
3x Deathrender
Creatures
1x Havoc Demon
2x Xathrid Demon
1x Woebringer Demon
2x Puppeteer Clique
2x Deathgreeter
4x Blood Speaker
2x Necrotic Sliver
4x Kami of False Hope
4x Blood Pet
2x Teysa, Orzhov Scion
4x Karmic Guide
Enchantments
3x Enduring Renewal
Land
8x Plains
8x Swamp
4x Terramorphic Expanse
Spells
4x Makeshift Mannequin
1x Damnation
1x Decree of Pain


I need some advise on getting a less steep ramp and get things out quicker on a consistent basis, particularly the renewal and the Deathrender. I am trying to do that while keeping enough demons in there for flavor purposes.
