Taking a closer looks at chant, it could be worth it for the ten card mill, plus non creatures go into your hand, so I'll definitely think about it if I can find it in trade. Thanks.

If you want enter the battlefield effects to combo with Living Death , Acidic Slime could act as repeatable removal, especially with your reanimation effects. Snapcaster Mage is quite expensive but another good ETB effect.

Regrowth acts as another Eternal Witness which can be very helpful. I know you're looking to get stuff in graveyard rather than hand but Worldly Tutor and Mystical Tutor are very versatile and should at least be considered just because they can help in almost any situation.

Mind Funeral and Mind Grind act as extra mill.

Forbidden Alchemy , Grisly Salvage , Mulch and Tracker's Instincts could help with milling and are great card advantage.

Laboratory Maniac could certainly be a win condition in this deck.

Considering how much this deck gets into the graveyard - Mortivore , Artisan of Kozilek , Lord of Extinction , Sewer Nemesis and Boneyard Wurm are worth considering as huge reanimation targets.

Hope this helps!

Oh and Golgari Grave-Troll has a huge dredge ability which could prove very helpful.

Tunnel Vision is an old favourite of mine. Naming Living Death of course. It's a bit risky, but since it fills your bin and tutors the exact card you want, you really can't go wrong.

Yeah I think ill be adding that.

Have you tried Jarad, Golgari Lich Lord ? Throwing as much as you are into your graveyard he should either be quite beefy himself or if you pull him plus a horde of other creatures with Living Death you can just start flinging fatties to hit all opponents at once. I have always thought that Jarad combos superbly with Consuming Aberration .

you're running Reanimator, si? Eldrazis are going to be your best friend. Pathrazer of Ulamog , Ulamog's Crusher , and Artisan of Kozilek are cheap Eldrazis that are going to be your best friends.

+1 from me

Have you thought of using any dredgers? Or mimeoplasm combos like Death's Shadow and Gaea's Revenge

Take a look at my deck I'm baaaaack!

If you're decking yourself you could just run Laboratory Maniac.
