My goal is to make this deck able to get cards in the graveyard at low cost.

This deck has a lot of combos, The most powerful one is that following.

Venser the sojourner (In play) + Timewarp + Eternal witness (In play) = Unlimited turns = I win. (5 mana)

Any suggestions?

I get pretty much what I want, with cards such as Bribery, Demonic Tutor, Bringer of the black dawn, Eternal witness.

In addition, with Recurring Nightmare, Karmic Guide, Rise from the grave, I can resurrect every turn the desired card. Moreover, the desired card will bring some nasty effect (Angel of Despair, Eternal Witness, Fleshbag Marauder, Coiling Oracle, Simulacrum, etc…) Technically I can cycle the combo indefinitely. With enough mana, (Timewarp, Recurring nightmare, eternal witness) = I win.

This deck is built in a spirit of group setting. It apparent chaos hides a lot of combo for the seasoned eye.

I like your burn deck, it does pack a lot of power. However, you will run out of steam in a group format game. (On average you will take out one player, then die)

But in tournament as it is intended it would be dangerous
