Most decks aren't playing anything bigger than a restoration angel. If I come up against a deck with Eldrazi or something comparable, I'll be siding out my heavyweights with a quickness. Otherwise, it's a Trampling 8/8 for 4mana. Most decks just aren't able to handle that, even with a free creature.

Well thank you. In EDH you have your Commander(Melek in this case) and a 99card library. You can only have one copy of each card in your library other than basic lands. Usually EDH is played in a multiplayer, casual format.
Just some information for you. =)
As for the Phyrexian Metamorph, he was the only Clone ability that made the cut for this deck.

Are you talking about Mainboard or Sideboard for the slimes?
Im not sure how I feel about them though, I've tried them before, and they've never done much work for me...

Valid points. Thank you again for the help. I really want this deck to be as competitive as possible. I've really wanted to play Servitude in Standard

Haha.... My bad there, thank you for pointing that out.

I didn't think of nevermore actually, and Ive been afraid of the control matchup with this deck... That may just be the card for it. Thank you for the suggestion! Curious though... Because the thought of control matchups just occurred to me.... Which do you think would be more useful in the matchup, Nevermore or Sin Collector?

It worked really well. A little bit of a set-up, but, for the most part it played consistently. Playing giants out of anyone's grave is always fun

I've Thought Twice about that, but, Thought Scour mills me a little, which gives Snapcaster more targets and it costs 1 mana less than Think Twice does, letting me cast it turn 1 and/ore with more spells than Think Twice.

I thought about Grisly Salvage, but, one thing I've noticed with Zombies is their lack of draw power.... Thought scour replaces itself and throws a couple cards in the graveyard, which helps Varolz and such.... Not to mention.... Besides the Captain, it's the only other blue card in the mainboard

I like the Idea of this deck... However. You seem to be putting a lot of emphasis on big creatures without a lot of play in them. Don't get me wrong, most of the creatures are top picks, but, Stonefare Croc, Crowned Ceratok, and Splinterhead seem to be thrown in here because they can be. I don't see why Lotleth Troll isn't in here.... He throws guys into your graveyard to boost the Wurm, Splinterfright, and use with Varolz.... Not to mention the guy has Trample and Regenerate built in! I also think the Zombies of Standard could make an appearance in here, especially for a more aggressive take. Another critter you could consider would be Strangleroot Geist, he has haste and Undying, so, you can sac it to Varolz and give it a counter, and still swing with it.
Corpsejack Menace is alright in here, he makes are curve a tad higher, but, at the same point he's doubling our counters... Which can be really good if we're scavenging with Varolz or Playing Lotleth Troll. Or using the Undying abilities on Geist and/or Geralf's messenger.
With Varolz in here, we're looking for Value creatures, anything that has more power than it's CMC. This is where Zombies are amazing. Diregraf Ghoul and Gravecrawler are both 2 counters for 1 mana and the Crawler can make it's way onto the board time and time again.

As for the non-creature spells. Getting creatures into your grave is definitely what your trying for here, but, you don't want to be milling yourself out now. Mulch and Salvage seem like a little much especially when you have Splinterfright already on board. A playset of Grisly Salvage in here would get you your constant land drops along with giving you the bomb you may need at the time. Alpha Authority is alright, giving the creature Hexproof and forcing them into awkward situations, but again, I think we can find better cards for it's spot. Rancor could do a lot, with it's self-recursion. Think Twice could fill the place for extra removal. Even Treasure Find could be great here, if you mill your bomb, you don't have to worry.
Abrupt Decay and Putrefy are our main options for removal in here. I prefer to maindeck the Decays myself, just because they are 1 mana less to cast and they hit most of the creatures in the metagame.(agro vs agro can be a hard matchup) Where as I'll side in the Putrefy if I need to kill large creatures consistently.

Sorry about the long comment ^^
I have a friend that has been playing B/G Zombie agro for awhile and the playstyle here looks a lot like that.
Hopefully some of this helps!

I decided that it was very inconsistent with Slumbering Dragon, Treacherous Pit-Dweller, and such. I replaced them with Diregraf Ghouls and Gravecrawlers which seem to be doing better along with still being value creatures for Varolz... Still needs something for late-game though.... Suggestions?

I've updated the list, any opinions?

Very much so. Aside from the extra playset of slaughter games in the SB. =]

Gaze of Granite, Putrefy, and Slaughter games are great sideboard options. Giant growth, not so much

Thank you. Glad to help =]

The only red you have in the mainboard is searing spear and rampager, while both are good, Im not sure your should splash for just them when there are so many other powerful red/rakdos cards for this deck.
Vexing Devil, Dryad Militant, and Spike Jester/Mogg Flunkies are all creatures that are great value here with Varolz. Then you also have cards like Rakdos's Return and Clan defiance for some great damage mid-late game or some early pressure.
Deadbridge Goliath is a little big for this deck, 4 mana for a 5/5 is alright, but he has no abilities besides his own scavenge, you could switch him out of here for something a little more powerful.
The Rakdos Maze Runner, Exava, might do wonders in here.

Check out my Jund Aggro deck if you get a chance!

Im not a a big Modern player, so Im new to most of the cards. I haven't used Grapeshot before, and it spaced my mind that it was a sorcery. Thanks for pointing it out

Ive been torn on where the deathrites should go. But, That's a lot of extra mana that I could use for Varolz and scavenging. As for the elementals, Spark elemental I want to stay in here unless you know of a better option. Otherwise, it's 3 damage going at them and 3 counters for Varolz for 1CMC.

Thank you, I was unaware that my ritual was illegal

I love that troll, just not so sure where we'd fit him in. Love to though
