I understand it doesn't work with Dark-Dwellers but neither does Radiant Flames. Read the Bones probably isn't what you want to be targeting with Dark-Dwellers anyway, especially if you've already played one in a game. Personally I'd much rather target Crackling Doom, Abzan Charm, or Kolaghan's Command.

How so? With Read the Bones you're trying to draw cards and Truths lets you draw an extra at the cost of 1 life. Are you trying to tell me that your putting yourself in a bad position by drawing the card you want to target with Bring to Light?

It maybe a personal preference choice, but I think Painful Truths is better then Read the Bones more often then not. Obviously in a deck that is almost guarantied to hit the 3 colours.

I'd use Pit Fight instead of Prey upon honestly the instant speed is worth the extra mana IMO.
I also believe Belligerent Sliver should be cut for the 2 missing Striking Slivers. First Strike Deathtouch is what your going for after all. Striking turn 1 and Venom turn 2 will shut down most aggro decks right there until they deal with one of them.
Just my opinions, happy casting.

DedWards is correct, It's exactly why I don't play Bitter Ordeal in my mill deck. It would be so good if so.
702.68a Gravestorm is a triggered ability that functions on the stack. “Gravestorm” means “When
you cast this spell, put a copy of it onto the stack for each permanent that was put into a
graveyard from the battlefield this turn. If the spell has any targets, you may choose new targets
for any of the copies.”

LOL, Riiiiiiiight.

OK sounds good, we've got some room to work with. For starters I'll give you the link to my Golgari Commander deck just for some ideas and such. It's pretty competitive and I love playing it. It's the only commander deck I have so I went all out on it (currently foiling it out). But your gonna make yours a zombie thyme and nothing wrong with that.

For starters you need some acceleration in here. Sol Ring is an auto add in any deck allowed to run it. Thought Vessel is really good as well. Golgari Signet will help you as well even tho I don't run it I did before. The same goes for Jet Medallion.

Another card that is just bonkers is Skullclamp. Imagine the draw engine you can create with Gravcrawler that and another zombie in play. Speaking of card draw Phyrexian Arena is amazing. Damnable Pact is great mid to late game too. It can also be that killing blow to your opponent. Closely related to card draw is tutoring. Next to Imperial Seal (forget that it's to expensive even for me). Vampiric and Demonic are the way to go. Diabolic is ok but it's expensive and usually leaves you without mana open to cast the thing you went to get. Oh ya Dark Petition is def better then Diabolic as well. As log as you have spell mastery that is.

Now we move onto removal. I run about 20 removal spells. Some people think I'm crazy but screw them, I like to hate on other and everything the play (after all this is a Golgari deck. A few you should add are Maelstrom Pulse, Putrefy, and Beast Within. Among others.

Shit I gotta go. I'll write some more later.

Ok then, Drop the Banners for Chromatic Lantern. Then I'd use more instant pump spells to trigger heroic instead of the Ordeals. Stand Firm, Swift Justice, Titans Strength. Defiant Strike, Mizzium Skin are a few good 1 drops.

4x Lingering Souls with the only way to access black mana being Pentad Prism seems inconsistent.

Very true, there are some creatures you never want to attack like Prime Time. The devoid aspect of it could be useful in some match ups tho. Either way great deck it was just something that came to mind when I saw it.

A few questions before I suggest things here. Is this just for casual/ what format? Do you wanna maintain a low budget?

Very Nice! I wonder if Visions of Brutality would be better then Pillory? Lower cmc and it allows your opp to attack while punishing them.

Ratchet Bomb or Engineered Explosives for more hate against opponents tokens since they both destroy all tokens no matter their toughness. Which will let you play Hunted Horror with no reserve

Blight Mamba instead of Plague Myr. +4 Vines of the Vastwood +4 Rancor. -2 Titan Strength -2 Giant Growth -4 Brute Force.

Before I go all crazy suggesting cards, what's your budget and how competitive/mean do you want this to be?

Ya sorry that's kind of what I was implying.

Neither is Kor Firewalker. Teeg is useful against GR Tron tho.

Teeg prevents that. However in addition to Teeg I'd suggest running Pithing Needle in the SB for this as well, since it's rather versatile.

oh ya Birds of Paradise would probably be a better fit then the mystic.

Well I think the phoenix is the weakest cad now. It doesn't really fit the thyme or do much in terms of what you're trying to accomplish. However instead of Lace with Moonglove I just remembered Quietus Spike. It popped into head this morning and I thought of this build when it did.
