1: doesn't matter if you discard stuff if you got the necessary cards, 2: niv-mizzet's can begin only as early as turn 7, Chain of plasma allows this to happen in turn 5, and as long as you don't discard the lab nut, yer all set. I would however suggest you getting 1-2 more lab maniacs, as else you are rather vulnerable to: 1: him being the last card (le irony) and 2: milling can fuck you up, so this can increase you chances

There are still possibilities in standard... Stuff like lobber crew (tap, deal 1+ damage) can dish out the last damage just as cheap burns can aswell. I roll him with Rakdos, as dealing damage cheap is beneficial for both.

I think you've misunderstood master of cruelties quite a bit. 1: He needs to attack alone, thus legion loyalist wont get his battalion procc'd. 2: He reduces the opponents health to 1 if he's unblocked, not if he deals damage(this happens before damage is declared, hence why he won't deal damage if he's unblocked... Note this allows ninjutsu to make a one-hit kill)

I like the vigor idea (completly forgot the bugger :p) so def gonna find a spot for him :) Not going varolz because 1: im expecting him to get banned in all but standard because ridiculous; 2: i have a number of cards relying on stuff in graveyards, including my own (lord of extinction, sheoldred) so i'd rather boost them/have them be useful than buff my skullbriar, i find focusing only on your commander is silly if he gets wrecked every time you cast him. Also thanks for reminding me of getting stuff outta my graveyard ta me hand, but i think i'd rather grab a genesis and sac it somehow...

I'll have to question your 4 masters of cruelties, as you will rarely be able to win the turn you attack with him which definatly is prefered. The only ways you can do it are costly except for lava spike. I'd also recommend to get the shred-freaks out, since it basicly is a rakdos cackler with -1 toughness and haste, an issue exava fixes anyway. i'd say replace it with some splatter thugs. If unleashed a 3/3 firststriker, and without an amble blocker aswell. (Hellrider does not allow for a one-turn-kill with the master of cruelties, as attacking goes before being blocked, and the 1 damage hits before the opponent gets reduced to 1

i mentioned infinite combo because that was what i had previously tried which got shut down :p

I'm sorry, its "turtle" in the sense of turtling until the shepherd comes along

Like every relentless rats deck <.<

I know the pain of trying a infinite combo, then midgame realising it actually doesn't work ^^ so im glad to prevent that sad moment :)

Sorry to burst your bubble, but bond of agony requires you to pay as much mana as you pay life, and thus you'd need a total of 21 mana to cast a bond of agony boosted to 20 life.
What you would do in your combo, playing bond for X=0 mana, would mean you would be forced to pay the additional cost of 0 hp, dealing 0 damage to everyone else.
If it was to work as you had envisioned, there wouldn't be a X in the cards mana cost, and the card would have been stupidly OP because such an easy kill combo could be achieved.
I'd advice you to - in the future upon finding an infinite combo/a kill combo - to google "[cardname] rules" to see if how you think the card works is - by the rules - correct.

Not entirely sure, but as it says "enchanted player's >first< upkeep each turn" i honestly doubt you can stack paradox haze... Sorry if i just "wrecked" your deck

Alright then, Imagine i'd go with your TG/viral drake/blue and galv myr stuff. Now, as you imagine this, Tell me what i should cut. I know from experience i need lots of capability of applying charge counters without there already being one(i.e. proliferate), so the coretapper, infuser and energy chamber are set in stone. Thats already 16 cards including darksteel reactor.

I don't want to rely too much on myrs for 2 reasons: 1: only a third of my main "free" source of charge counters is from myrs, and 2: i already did that in my Hellkite tyrant myr deck, and while "if it works, don't fix it" is a valid point, innovation leads to new paths.
Training grounds currently doesn't benefit me all that much for me to deem worth it. Lowers cost of prototype portal by 1-2 (what i want to copy with it costs 2 mana, so 1 mana reduction due to "no less than 1". Contagion engine benefits from it, yes, but putting 4 cards in the deck for the sake of 3 cards is in my own opinion silly. Coupled with me planned to put locus' in the deck (you couldn't have known, i won't judge), keeping the amount of blue mana costs as low as possible is prefered. About braingeyser, i keep my decks modern (because derp) and i doubt card advantage will be my downfall.

Sidenote: Can't be infinite proliferation from the drake, as it will end up as 1U... Palladium is 2 colorless, and so is everflowing chalice.

IMO you have far too little white permanents for springjack shepherd to be worth it... If the mayority of your perms was white, you could possibly get 7 goats on the first springjack cast. I made a goat deck myself, ye can have a look if ye want http://www.mtgvault.com/thebeeja/decks/turtle-goat-deck/

Modern, guy. Dreadnaught is from mirage, which is before 8th edition

Considering that your deck idea is getting stuff in play cheaper through unexpected result, i'd suggest ye to stay off the door of nothingness, as it needs 10 colored mana after being cast, so you need 10 lands which can in total bring atleast 2 of every color, and as you hardly have mana accelleration (like mirari's wake and such) that will take a while.
Beyond that, i like the idea :)

You might want to get some library search to increase your chances of getting heartless summoning, as you currently have roughly 40% chance of having it on your start hand. There are also some demons im wondering as to why you have them:
- Nefarox, you might as well put in a demon with the same, or less, mana cost, like more ob nixilis instead of him, as you don't have a big reason to attack alone.
- Dread cacodemon. He taps all your stuff, and costs 2 more than reiver demon who, for the cost of 2 less in power/toughness, doesn't tap all your stuff (with restrictions) You got enough unconditional destroys already to welcome this 1 loss.
- Abyssal Persecutor, Just as awesome as desecration demon except you can't win with him in play. Seems like a waste of destroy to me, and killing him could give a gap in your "defense" that the opponent can take advantage of and kill you.

So to top it all off, my suggestions (feel free to not follow them if you find my argumentation pointless) are as following:
- Some search for your summoning (demonic/diabolic tutor works well)
- Grab a second rakdos lord of riots. With your endless supply of destroy it'll be easy to get a hit in to play him.
- get rid of nefarox, dread cacodemon and abyssal persecutor. more reiver demons, ob nixilis' and griselbrands
- Maybe get some multicolored lands ( i know they're expensive as hell, but having 3 demons, 2 heartless on your hand and only getting mountains will suck. Hard.
I hope it goes well with the deck, i've had the thought of using heartless for some demons aswell and am considering making a deck with it at some point :)

If you're thinking of blessings of nature, i already have it :p I don't really like the cocoon as i want to attack with briar alot, and if i do that, cocoon is gone. It is such a niche choice that i think i'll pass on it.
As i wrote in one of my earlier comments, i didn't like wiitigo due to the mana cost. I would have taken it if i had more mana fetch, but then i'd loose out on either some useful creatures or some other +1/+1 counter generation, or killspells which already are scarce in it.

Wrong, i don't see myself as a tryhard, hell, this is my first EDH deck. I just hate having lots of 6+ mana spells in my decks as i find them to come into play when its too late. Therefor stuff really needs to be worth it for me justifying expensive spells, and i find shape of the wiitigo to be replaceable by Increasing savagery

1 counter less for 2 mana less through increasing savagery
