Hi, I've though much about what deck can you build around Summoning Portal card. It's really hard to gain some value from this card, since it doesn't have attack, decent hp, and costs really much (you need to play at least two creatures to justify it's cost). The "minimum one mana cost" rule adds another restriction, that slows us significally (else two summoning portals would mean 0-cost 4 mana creatures). But I have an idea of getting something usefull, or at least funny from this card.
Are you with me?

Then let's summarize what I've got by far:

• Emperor Thaurissan + Summoning Portal -> 3-mana creatures cost zero. We can get rid of one mana restriction this way. So magic mana cost numbers is 3 and 5 (for one portal and for two).
• Giants lower their mana cost below 1, so Sea Giant can be easily put for 0.
• Questing Adventurer has insane synergy with this deck. He grows giant size really fast.
• We can use creatures that draw card(s) on battlecry, and put them cheap while Summoning Portal is on the field. That way we can keep engines running.
• We can't really use token-generating creatures like Imp Gang Boss, because we run into 7-creature limits very fast. Portal(s) take some space by themselves.
• We need taunts to keep portals and hero protected.
• Do I miss something else? Some synergy that I don't see?

Deck I'm using now (it's far from perfect, but point up, what cards would you add or remove):

It's plays much like handlock on the beginning (that way we have cards to vomit), and plays thaurissan and portals later in the game.

This concept is green and new, hope you may bring me some ideas.

Cuz, as I said earlier, it plays much like handlock early. Best playline is something like this:

T1: nothing
T2: tap
T3: tap
* nets huge card advantage *
T4: Drake / Giant / Hellfire
T5: taunt up
* regain tempo, may be low on HP on this point *
T6: Emperor Thaurissan
T7: Portal -> stuff (healing up, taunting, dropping threats, gaining cards etc)

Novice Engineer value is unlikely, cuz we really don't want 1/1 body when max creature limit is that low.

Giants - is there some testing behind their composition? I find a single Mountain and a single Sea with no Moltens suspicious at least and can see different composition working better, maybe add some (instead of the Faceless Manipulator that typically "just" generates another Giant anyway and one Imp-losion maybe?)

Nope, this deck isn't a final version, just an example of deck that can play vomit as wincon.
Actually, you and I think alike. I've removed all Imp-losion for 2x giants.
I'm not sure about Faceless Manipulator, because he can be played as cheap giant(can even copy taunted giant) or even better.

It's good in-depth vulnerability analisys, i'll try to answer.

- vs Aggro

 Agree, this matchup isn't that good. I have heal, but that's too slow generally.

Quote from DreySF jump

- vs. Midrange the deck may work when you have awesome draw. On average draw Midrange will be able to do enough damage output and reach for leathal before you can establish your win condition (vomit).

General opener (handlock) gives enough tempo to live up to vomit. It's consistent enough.

Quote from DreySF jump

- vs. Control the deck will see almost no light. Freeze Mage will not care; Ctrl Warrior will Brawl (and will also be able to remove your erly threats effectively);

 Freeze mage don't have direct damage lethal as early as I can vomit (taunts later), and don't have enough AoE to clear the whole board.

Quote from DreySF jump

- vs. Combo the deck will suffer. Oil Rouge will simply outtempo you and also be able to clear the board with Bladefury.

 Would need some serious weapon buffs to clear giant size creatures tho.

Quote from DreySF jump

It is not clear what your win condition is. Compared to Handlock you don't have "enough" giants and compared to Zoo you lack burst potential. Also, your comback mechanism is not obious  (imho not present) after board clear (you will end up with no cards and no board after vomit). Simply by "having" minions on board will not result in you winning games often.

 Generally, I have lots of cards in hand to back up vomit, thanks to Gnomish Inventor, Azure Drake and Coldlight Oracle. Sometimes I can even spend my mana to tap during vomit and still be at 7 creatures max. So after I lose a board, I can go for handlock creatures or second vomit (given, only one portal was used first time). Having lot of healing and being able to cheat that much big creatures/taunts on the field in short amount of time is my win condition (apart from just pure giant handlock wincon).

Edit: And ye, compared to handlock I have enough giants, as Questing Adventurer easily counts as one.

Wait actually, how does Summoning Portal work? 
By its wording, it would seem as your cards could NEVER get below 1 mana, even from other effects like Emperor Thaurissan. But knowing Hearthstones simplified/casual card text format it might not be that way.
Anyhow, has it been tested?

Quote from DreySF jump

Again I'm not saying the idea is bad or something, just that you need to tackle the meta. You need to contest your deck against the meta.

 It's yet to be tested and changed, really. That list may change dramatically, I wouldn't be surpriced if ~8-10 card swaps will make this deck stronger than it is now.

I've already encountered lack of silence, btw, when I went against Sylvanas. Need to tweak it this way atleast. Probably should take 4 mana silence, since it could synergize with portal theme better.

Anyhow, has it been tested?

 It works like this: Summoning Portal never lowers past 1 mana, but mana cost is getting lowered by other sources (giants, Thaurissan) - it can get past this point. So even a single proc of Emperor Thaurissan gives all your hand 0-cost potential.

My second take on building Vomit deck. I've removed card-drawing cards completely, added two silence cards, added Loatheb (helps to save our deck after vomiting), Molten Giant (cuz we run low on HP nearly every game, it's time to abuse it and turn into comeback tech).

Harrison Jones is a test card, might remove it, but it's manacost fits, stats are fine, and it may do awesome effect and possible Death's Bite deathrattle disrupting.

Just kinda spitballing but what about adding 1-2 Void Terrors?  It would help with the problem of possibly having a full board if you needed to clear space AND these could possibly add some really nice punch

That's good idea actually. I'll try to build something with it.

I've added Void Terrors, get rid of hand-style, and made this deck look more like zoo.

Check out for description inside.

I didn't expect this, but I have big success with this deck. It has decent start and a lot of comeback techs.

Best thing about Sacrificial Pact is 0-mana cost. It can be used the same turn you drop moltens and require healing to be alive. Generally you kill some 1/1 with it, so no big loss. And it also triggers Cult Master. In face race matchups this 5 hp can really matter.

Sacrificial Pact can also do good stuff against other warlocks, just need to remember that you can actually do that.

Probably Mal'Ganis can perform the same role, but I believe he is much slower. I don't have any of them to playtest it, tho. You can try and say how it works for you and describe your feelings playing this deck.

This is looking very interesting.  Have you found Demonwrath useful?  It looks like you may not have enough demons to run it well, unless you get it very early.  Would Hellfire work better, it would synergize with Molten Giants

Also, and this again is without having play tested this deck at all, the other card that seems out of place is Cult Master but maybe that is a personal preference since I don't run him in many of my warlock decks.

I still don't sure about Demonwrath or Hellfire choice.

Hellfire removes patrons, hellfire removes mechs. But with demonwrath you could do sick stuff like t2 egg t3 demonwrath. Also you don't really want 3 damage to face when you play against aggro. You will get on Molten Giant range one way or another. And with demonwhath you sometimes can AoE enemy board only, leaving your demons unhurt (giants probably don't care much).

Cult Master is there because we don't tap as much as handlock, and we slowly running off steam. Vomit(putting stuff after Summoning Portal) only makes it worse: we run off steam really fast when we vomit. And it's just good thing to have more cards, more options (have giants when we can cheat them, have heals when we need them etc). Cult Master can give at least 2-3 cards when it lands on the board if you play him in the right time, have bunch of synergies (tokens, [card] Void Terror[/card], [card]Sacrificial Pact[/card]). 4/2 is also good for Shadowflame. And it combos with vomit pretty nice.

Siphon Soul doesn't solve anything, since we have 2x Shadowflame and giants to clear nearly everything with a single AoE. It's too slow against aggro, tempo, useless against combo, only useful against some midrange / control minions, and there are lot of them who aren't just as easy to get rid, like Sylvanas and Dr. Balance. And it's 6 mana, which is slow.

Bane of Doom singleton may work (it's big value), but I don't like heavy-RNG cards.

Mistress of Pain + Power Overwhelming is much worse than [card]Sacrificial Pact[/card]+demon (preferrably Imp-losion). First of all, and the most important, mistress need to survive a single turn, while pact is used the same turn you need it. Then, it's only 5 HP healing, same as with pact. And it costs 1 mana vs 0 mana. And third, Power Overwhelming already has so much better uses. Combo with Shadowflame, Nerubian Egg, Void Terror, and just plainly reaching lethal range.
