Dream Halls, of the Dead

Ever since I heard of the card [[Dream Halls]] I've wanted to build around it.

Recently the idea popped into my head again and I immediately thought of [[Necrotic Ooze]].

Both of them revolve around the graveyard and cheating things into play which are my favorite deck Archetypes in Magic. Dead things. And fat surprises.

So I started throwing cards together under the heading of Sidisi.

My goal is get everything into the graveyard, almost Hermit Druid style. Then use hilarious interactions of Necrotic Ooze and Dream Halls to derp around for a while. I don't just want this to be a Laboratory Maniac deck, trying to dump my grave solely to win with his draw. I want it more to be a constant loop from between the battlefield and the graveyard using cards like [[Bitter Ordeal]] out of nowhere when I've put my whole library into my grave three times in the course of a turn.

I'm having some trouble however. With Necrotic Ooze and Dream Halls being such unique cards I've run into some questions.

How does Necrotic Ooze work with Names? For things like [[Spellskite]] and [[Morphling]], their abilities have their name in them directly, does this mean I cannot target N.Ooze with them?

Also can I use [[Nullmage Shepherd]]'s ability, or [[Gravespawn Sovereign]] with the Ooze?

Secondly, if a [[Havengul Lich]] is in the Yard, with Ooze and Dream Halls on the field, can I pay 1 colorless then discard a card using Dream Halls ability to cast the targeted creature? Also does Dream Halls work with things like Flashback?

All this being said, I'm also in need of some help dumping my grave. My optimal ways so far are not my favorite but functional:

[[Tunnel Vision]] + [[Viscera Seer]] one hit wonder

[[Gravecrawler]] + a zombie + [[Phyrexian Altar]] + [[Grim Haruspex]]

[[Aphetto Alchemist]] + [[Mesmeric Orb]] + [[Worldspine Wurm]] (one of the infinites in the deck, I don't usually like infinite-ing, but all those Zombies (Sidisi) with a [[Shepherd of Rot]] seems too sadistic)

I'm including things like [[Nacromeba]] and [[Bloodghast]] to fuel a [[Dread Return]] targeting Ooze most likely. I know I'm not the first to build this type of graveyard "combo" deck, but I'm just looking for a few nudges in the right direction. (Also for cool Yard interaction cards like [[Pedantic Learning]])
