What can seriously make this good is the fact that you have a free mulligan if you have no land in your hand. So unlimited mulligan until you get perfect hand?

/ nvm, apparently you have to still drop one card per mulligan

Have you thought of an official name for this deck? How does "All for none" or "Madman's Redemption" sound? btw Would sideboarding a Sol Ring help at all in Vintage?

You COULD replace the Cabal Therapy with a Sol Ring , one more Wild Cantor and one more Dread Return (that can still be used with a Chrome Mox ).Keeping in mind this is just trying to stay tournament legal.

Now that I think about it, if you have one of the combo cards in hand, for example Laboratory Maniac , but no Cabal Therapy in hand, you could mill, wait for the four Narcomoeba to return to the field, then pay Cabal Therapy 's flashback cost by sacking one Narcomoeba or what you milled yourself with, discard Laboratory Maniac and leave the remaining three or four for Dread Return 's flashback and continue with the combo. Now what if that were to happen but with one or even two Narcomoeba still in hand? Just wait for the other ones to return to the field and use what you milled yourself with as part of the flashback cost for Dread Return , whether it's Balustrade Spy or Undercity Informer .
Have two combo cards in hand at once (EVEN A Narcomoeba MAKING THREE)?! Azami, Lady of Scrolls and Angel of Glory's Rise still in hand?! Hopeless?! Nope. If possible, play Summoner's Pact to get a Spirit guide and/or just sack a Spirit guide to play a Wild Cantor . (Should have minimum 5 creatures on field by this point, including (possible) 3 Narcomoeba .) Sack two creatures by casting two seperate Cabal Therapy flashback costs, and discard the two (or three) combo cards. Then continue with the combo. For this case specifically, if a Wild Cantor can't be played, you're out of luck, or if you've still got a Narcomoeba in hand, try messing around with remaining mana in your pool. Still damn beautiful.
TL;DR Weebles wobble but they don't fall down!

Sorry, I don't mean to spam but in the last paragraph, by sacking two combo cards I meant Azami, Lady of Scrolls and Angel of Glory's Rise so the combo can still work. I'm gonna wait for others to talk before I do again, whew. I'm constructing this deck for sure.

nvm again, it's on Star City Games: "Oops, All the Spells!"

+1 from me

What if Dread Return is in your starting hand or draw? You "full" your hand and discard it in the cleanup step? Isn't that "pause" dangerous?

That's why you have Cabal Therapy You get 4 Narcomoeba back, so you can sacrifice one to discard a card that must be in the graveyard (like Dread Return for example)

Oh! I see!

Ops all spells... An Underworld Cerberus Build is more reliable.

I don't see how an Underworld Cerberus would work with this deck, could you elaborate?

Ah legacy, the place where crazy combos are awesome and people don't understand how they work <3

Underworld Cerberus victory frees up a card slot, which is, by itself, better. It also minimizes dead hands resulting from drawing into combo components: in a deck using the Angel as a Dread Return target, drawing Angel of Glory's Rise , Laboratory Maniac , Dread Return , or Azami is problematic, whereas a deck using the Cerberus only has to worry about drawing the Cerberus itself or drawing Dread Return. This is a considerable improvement over the Angel-based method.

Scenario: Opening hand #1: Summoner's Pact, Undercity Informer, Simian Spirit Guide, Dark Ritual, Cabal Ritual, Dread Return, Simian Spirit Guide

I keep. I exile a Simian Spirit Guide and use the mana to cast Wild Cantor . I sacrifice Wild Cantor for a black mana and use the black mana to play Dark Ritual . I use two of the mana from Dark Ritual to play Cabal Ritual . That gives me a total of four black mana. I cast Undercity Informer and use my last remaining mana to activate its ability, putting my library into my graveyard and four Narcomoeba 's onto the battlefield. I sacrifice a Narcomoeba to flashback Cabal Therapy, targeting myself and naming Dread Return , which I then discard. I also get a zombie token thanks to Bridge from Below . I sacrifice a Narcomoeba to flashback Cabal Therapy on my opponent, naming whatever card I suspect might be a problem and getting another zombie token. If I see something that it still threatening, I sacrifice a third Narcomoeba to flashback my last Cabal Therapy and get rid of it, possibly getting another zombie token if my opponent hadn't already had any cards discarded. I then sacrifice three creatures, say one Narcomoeba and two zombie tokens, to flashback Dread Return targeting Underworld Cerberus . All of my creatures in my graveyard go to my hand. I exile a Simian http://static.tappedout.net/None_medium.jpgSpirit Guide for a red mana and use it to play Wild Cantor . I exile two Elvish Spirit Guide 's for two mana, sacrifice Wild Cantor for a blue mana, and cast Laboratory Maniac . With the Maniac on the battlefield, I cycle a Street Wraith and win

I forgot to add that your using Cabal Therapy to sac Underworld Cerberus in order to get all your mana gen back in hand.

The way the milling rule works is that if you mill until you hit a land and don't get one you lose right their. This gives you no time to play any additional cards once you use one of your mill cards. Your dead before you can do anything. Sorry to say.

You lose once you can't "draw"

The milling effect of this deck doesn't make you draw, it makes you reveal the card, so you will be fine :)

Noob question here, but anyways: How do you tap a Wizard on turn one? Wouldn't any card sent to battlefield from graveyard have summoning sickness until turn 2?Is it because Azami, Lady of Scrolls 's activated ability technically bypasses the "no tap rule", since it doesn't have the "tap" symbol in its wording?Or am I missing something else?

In any case, an amazing deck!

what is the use of Spoils of the Vault ? superb deck!!!!

CapnAhab, your scenario uses 4 Cabal Therapy and this deck only has 3.

How does Spoils of the Vault work on this deck?

Thanks!

How do you use Undercity Informer's ability if you can't sac a creature.

he sacs himself
