guardianangel731 Thanks! :D

Watch out for Kambal, Consul of Allocation, he will slow you down, and possibly make it not possible for you to win so easily. i understand the increasing lifegain is awesome, but just remember that. other than that, i love the deck. +1

Awesome idea.

Have you considered Glint-Nest Crane ?I think it's more immediately effective then Smuggler's Copter despite the artifact synergy. I'll try it out and let you know.

Have you considered putting in Inventor's fair? Even in the side board.

Illusys Yeah, that seems like a good idea. My only concern is that it's not as big of a body, but otherwise, it seems pretty good! Let me know how that testing goes.

jennywalker0 I like that idea. I'm going to take an island out and put an Inventor's Fair in.

Everyone seems to forget, X-Drops are also castable for 0.

Endless One

Another note - This combo is more feasible than it appears. Aetherflux Reservoir's lifegain ability goes on the stack and doesn't count the number of cast spells until it resolves. Thus, you only need to cast 6 spells in a single turn with it in play to gain the 31+ life (assuming you are still at 20) needed to win the game, provided you can cast all 6 spells BEFORE the first ability resolves.

Also, you need to keep some counters in hand in case your opponent pings you for lethal damage after you pay 50 life, if you die before Aetherflux Reservoir's 50 damage is dealt (since it also uses the stack), you lose.

Can I steal this and try to build a modern version?

maddoxmtg Sure, go ahead. There actually is a modern archetype very similar to this, it is called "Cheerios". However, have fun brewing!

jp9506 I was actually thinking about adding Endless One. However, you wouldn't cast him for 0, because you want to hit things with Paradoxical Outcome. Hopefully, you have either Herald of Kozilek or Foundry Inspector out to actually cast him for more than 0. I actually might add a few counterspells to the sideboard. I like that idea. I love the new counterspell, Revolutionary Rebuff. But, usually, your life total after getting off the combo can take a few hits. Also, I don't know if there was an error in your calculations, but according to mine, 6 triggers off of Aetherflux Reservoir only nets you 21 life (1 + 2 + 3 + 4 + 5 + 6 = 21). You should need 8 triggers to get you over the 50 life mark. (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36) But otherwise, I like both of your ideas.

jp9506 After giving it some more thought, I realized that I actually really like Endless One. It acts as a blocker, and can be cast basically for free if needed. I'm going to maindeck it right now. i also forgot that Endless One's cost can't be reduced by Foundry Inspector, but I still like the idea.

JardBard I play legacy cheerios. But modern is kind of to-do. I'm looking at building a sort of storm-eggs build.

maddoxmtg That actually sounds pretty interesting. Do you mind if you send me the link to the deck page when you're done? I'd want to see that.

Is Crush of Tentacles not what this deck needs? It seems easy to Surge. And sure, your board gets put back in your hand but it's pretty easy to recast everything which only helps gain more life. I don't know, I'm probably wrong. Sweet deck though regardless!

JardBard

You are misunderstanding how the stack works. Best way to explain it is as follows.

Cast Aetherflux Reservoir, allow it to resolve. Your life total is 20.

Cast some random card (call it card A), place it on the stack, place Aetherflux's lifegain ability on the stack. Your life total is STILL 20.

Cast another spell (card B), it goes on the stack on top of Aetherflux's ability, add a second Aetherflux ability to the stack on top. Still at 20 life.

Repeat 4 more times (Cards C - F).

Now on the stack from top to bottom we have:

Aetherflux, F, Aetherflux, E, Aetherflux, D, Aetherflux, C, Aetherflux, B, Aetherflux, A

And we are still at 20 life.

Now we allow the stack to resolve...

We start with an Aetherflux lifegain ability since it is on top, how many spells did we cast this turn? 7 (A, B, C, D, E, F, and Aetherflux)

Resolves... 20 + 7 = 27

F then resolves

Aetherflux again, still the same 7 casts, so 27 + 7 = 34

E resolves

Aetherflux again, still the same 7 casts, so 34 + 7 = 41

D resolves

Aetherflux again, still the same 7 casts, so 41 + 7 = 48

C resolves

Aetherflux again, still the same 7 casts, so 48 + 7 = 55

B resolves

Aetherflux again, still the same 7 casts, so 55 + 7 = 62

A resolves

End result, Aetherflux Reservoir doesn't care when you cast the spell, it only counts how many were cast when its ability resolves. Now for you to use Paradoxical Outcome, you have to let the stack resolve so that you have targets to bring back into your hand. Using that, you could pull it off with only 3 0-Drops. Assuming Aetherflux was cast on a previous turn, 20 + 3 + 3 + 3 + 4 + 7 + 7 + 7 = 54

Well, jp9506 you are failing to understand how rules work with the stack. You can not cast anything in this deck except paradoxical outcome unless the stack is completely empty. Nothing has flash, so you can cast anything until after each aetherflux ability resolves.

maddoxmtg

That was how it was explained to me, and at the time everything involved was instant speed, so it worked.

I wasn't thinking about the fact that the majority of the cards we are talking about are sorceries, artifacts, and creatures. My bad.

Let me rephrase by saying, using instant-speed cards, it is possible to achieve the required life total much faster (6 spells).

Okay man, here's the thing that few people realise about Panharmonicon: regular ETB effects don't trigger twice off of it. So like the entire idea of more draw power off your artifacts ETB isn't quite accurate. The way Panharmonicon works is based off something triggering the ETB effects of a card you already control i.e.: Ally Rally effects. So if say you control Tajuru Beastmaster and you get another ally coming in Tajuru's effect triggers twice.

Umm no. At the time of entering the battlefield, you control that permanent. There for the trigger on the permanent will occur twice. Additionally, cards like Soul's Attendant which triggers whenever a creatures enters the battlefield under anyone's control, will also trigger twice.

I've been playing around with this a bit and while Panharmonicon is great at pushing you over the top, the deck functions just fine without it. I swapped it out with Glint-Nest Crane which smooths out your early draws very nicely, is very happy to get bounced back to your hand when you want to go off and is a blocker with flying in a pinch. It hurt my soul to cut such a cool card but i think its more consistent without it.

Illusys Yeah, I've been testing it too, but I think I like Panharmonicon too much to take it out. I really like Glint-Nest Crane, but I feel that it is better to replace Filigree Familiar. Sure, it gets card draw and life, but I don't feel that 2 life is really that important in that state of the early game, and later on when you draw it it's almost a dead draw because you're going to gain a massive amount anyways. In my opinion, I think Glint-Nest Crane feels better there.

Yeah, i understand completely, Panharmonicon is super fun and flavorful. Also it double triggers much better with Glint-Nest Crane then Filigree Familiar

I keep going back and forth between 2 filigree familiar or 2 panharmonicon. My issue with panharmonicon is that it doesnt do much early on and you almost never want to cast it for 4. I think 2 is the most I would want to run.

this is the list i've adjusted from yourshttp://tappedout.net/mtg-decks/19-09-16-kld-aetherflux-reservoir-combo-copy/

Also, i highly recommend Terrarion. It allows you to drop Smoldering Marsh for 1x Nephalia Academy (extremely relevant and underrated card against any black control especially post sideboard) and1x Sequestered Stash (super handy utility in a pinch). Also it makes casting Lost Legacy out of the sideboard much more reliable as well as Ruinous Path for me. I've found esper walkers is a really tough matchup, so i feel the sideboard needs something to deal with planeswalkers. If not ruinous path then maybe Imprisoned in the Moon but if you have terrarion the double black isnt that big of a deal.

this set and this deck might be my favorite MTG experience ever, major kudos on the idea

Hi, I actually have a very similar deck to this that I created. I recommend you check it out over at Standard Artifact Storm!

In regards to your land base, I recommend adding a set of Aether Hub. They're great as untapped lands that can be used for any color, allowing you to play Glint-Nest Crane and Herald of Kozilek easily before getting Prophetic Prism on the board.

@K_Train ooo good call, i thought Aether Hub came into play tapped for some reason, i'll definitely add some to my version.

Illusys Yeah, I originally had Terrarion in the deck, but I took it out because I didn't like it entering tapped. But the more that I think about it, the better I like it. I'll probably switch out the Cathar's Shields for them. And yes, I was also thinking about the planeswalker problem, and I don't think Unlicensed Disintegration is enough when it only hits them for 3 damage. I'll probably end up going Imprisoned in the Moon over Ruinous Path, because the single blue is easier to pay than the double black, like you said.This deck has also been a great MTG experience for me, and I really like this new set a lot. Thanks. :)

K_Train I checked out the deck you had, and it seems pretty similiar, I like the alternate wincon. Actually, the original version of this deck that I made not only had Reckless Fireweaver, but I also had a set of Nettle Drone to ping for even more. And about Aether Hub, I like the idea, but from my playtesting of this deck, there isn't really a problem early game with mana color. Also, there's no way for us to make energy, so it just taps for colorless later. Maybe I would consider it if I didn't have Evolving Wilds in the deck. This is because, to put Aether Hub in, I would probably have to take out some basics, which would hurt Evolving Wilds' ability to bring out basics. Thanks for the idea, though.

Nice deck!

I have a similar one here if you want to take a look for some ideas. I hope you don't mind, I can give credit if you want, but I took some ideas from here for the sideboard.

I also noticed in your description that you said Panharmonicon doubles the counters on Endless One when it enters with pan out. This unfortunately doesn't work like that. The ability of Endless One entering and the counters going on it is (I believe) a replacement effect that changes how it enters the battlefield.

A triggered ability is defined as this:

603.1. Triggered abilities have a trigger condition and an effect. They are written as [Trigger condition], [effect], and begin with the word when, whenever, or at. They can also be expressed as [When/Whenever/At] [trigger event], [effect].

Other than that, it seems like a solid deck!
