The Eldeazi should show up here: It that Betrays and Artisan of Kozilek especially.
Diabolic Tutor costs too much to be effective, demonic tutor is better. Reanimate should be added too

Alright so I draw 10 hands and mulled until I had the Crusher in hand. 6 out of the 10 I didn't even draw into him meaning you have a 60% chance of doing ABSOLUTELY NOTHING THE WHOLE GAME!
Now, from there you are assuming that you will be able to cast him, but usually he'll be countered, and if he's not then he will be killed over the course of the next turn because he doesn't have haste. Or any Fog effect would lol because you end the turn by sacing your only creature.
GG.

You also NEED 99 cards in your deck. You can't run more or less.
Nev's Disk, Sunder, Sunderinf Titan, Time Stop, Channel, Phyrexian Metamorph, Sensei's Top, lots of counter spells, Evacuation, Savor the Monent, Karn Liberated, JtMS, Tamiyo.

Disclaimer: no offense meant--it's hard to come up with original decks and many of my dabblings end up poorly conceived.
Sanguine Bond is too costly and conditional to be effective. Same with Falkenrath Noble. Bottle Gnome's life gain is largely irrelevant. Hatred costs too much but is powerful enough to be relevant; you should probably run 1 or 2. Myr Welder is too high of a cost and too small of a board presence in most games. Illusionist's Braces doesn't really work well in this deck because D of the Vault's and Blood Artist's are trigger and not activated effects. And you should cut your lands down to between 14 to 16.
That frees up 22-25 cards to be added. 4 Archbound Ravagers are a must--awesome synergy. 3 Cranial Plating. 4 Vault Skirge. 3 Etching Champion. 4 Myr Retriever. 4 Mox Opal. 2 or 3 Steel Overseer or Signal Pests.
If the Mox Opals are too expensive for you budget then put in Springleaf Drum.
Hope this is helpful!

Here's a list of placing mono black Legacy decks:

Hope this helps!

Midnight banchee seems too expensive, even as a 1 of. And I don't think thrill kill assassin is necessary with your kill spells. And 1 less Nantuko would make room for 4 rituals.
I was also thinking, why not have phyrexian Oblitorators in here?
Other than that you should think about discard effects like Hymn of tourach, thought seize, inquisition of Kozilek, etc.

Dash Hopes would be a good card to think about adding. With such a large board presence they would likely let their spell get countered rather than give up 5 life that you're going to beat out if them anyway. Dark Ritual too since this is Legacy.

I'm pretty sure this is standard but it's true: people dot want to let the Hydra stay for long. Ranger's Guile is a good answer to most removal.

I don't think you should run Life and Limb because any Wrath of God kind of spell would destroy all of your lands.

I see your point. I don't think Loyalist would be great main board in this deck because it would likely be turn 4 before the battalion ability would trigger. Stromkirk Noble wouldn't be bad, if he survives the first couple of turns he'll be a 3/3 or bigger and you can soul bond him for lifelink or doublestrike.
Loyalist is a great sideboard card against Token decks.

Rise From the Grave is too slow for Legacy. Add Reanimate and/or Exhume so you can reanimate turn 1. Also you should look up Reya Dawnbringer, Artisan of Kozilek, It that Betrays, and other Eldrazi that don't reshuffle your graveyard.

This looks like a reasonably good deck. In my opinion Treasured Find should be more creatures (probably with Dredge) so you can utilize Jarad and Voralz fully. The other minor issue is you should have more duel lands (Overgrown Tomb and Woodland Cemetry) because Predator Ooze and Grqve Pact have opposite mana requirements and 3 or each could be hard to get a hold of without them.

It's largely aggro and reanimator.
Check out this site: http://www.mtgtop8.com/format?f=ST&meta=50 And switch it to "the last 2 weeks" to see what the meta's like. No one sideboards to stop mill except for the rare Esper deck expecting a mirror match.

Looks good. I would run 4 mayor of Avabrucks though. The lands look good but I think if you added 4 Guildgates by cutting 3 plains and a forest (playing them in the mid game when the mana isn't needed or T1 to set up for larger Cmc hands) could be beneficial. Play test it and see if it works or if the tap effect ends up being detrimental.
Hope this helps!

Also, Flooded Grove doesn't fix the mana issue--in fact it only makes it worse. Unless you have a guild gate out then you can only tap for colorless mana so all your creatures are unplayable.

Lol you don't need more than one phage on the board ever. Just strap unblockable to her and win. You don't win by scaring your opponent(unless you scare them so much they scoop)
I'm still wait for a reason to run so many clone effects unless the plan is to copy your opponents creature but that relies on them have relevant cards to clone. Otherwise your just cloning Invisible Stalker..

You have no way of generating red mana so why run 4 Stensia Bloodhalls?

Yes but you can compensate for some of it by running 4 Exavas and more Rakdos cards like Gorehouse Chainwalker. It's already been confirmed that Shock is coming back in M14. Searing Spear and TSlip don't have good replacements yet but that may come in Theros. Hell rider is getting an Ogre Replacement in M14, not the same ability but fills the same slot I think.

I agree it's not great but with Reconers and the Pilgrim you don't really have to worry overly much about a T1 blocker. And any control deck would take the 4 anyway on turn 1 because they won't have an answer before it swings in. It's not bad but you should play rest some other 1 drops to see if they're better.

M13 rotates out when Theros comes in, not when M14 does.
