Cloud Key Discussion

Barookie on Kozilek, the Artifact Distortion

Cippo Yeah I am thinking about actually buying this deck so want to hold off on some of the more expensive ramps. I didn't even know Eye of Ugin existed so thanks for mentioning it. Also Cloud Key seems like a good replacement for Foundry Inspector, I would say the same for Semblance Anvil too.

Cippo on Kozilek, the Artifact Distortion

Cloud Key or Semblance Anvil might be more useful than Foundry Inspector since those can reduce creature costs or artifact costs.

You're missing some of the more expensive rocks like Mana Vault, Mana Crypt, and Grim Monolith but those are price heavy cards.

I'd definitely throw Eye of Ugin in there.

As a fellow Karn combo player, I love the combos you have going on. So few people run the infinite mana damage outlet.

Goblin Cannon is criminally underrated but you're missing the godly mana outlet: Walking Ballista. He's free to find with Citanul Flute and Eye of Ugin can grab him too.

You have an additional unmentioned combo in here that I love btw. Krark-Clan Ironworks + Myr Retriever + Scrap Trawler + Basalt Monolith/Cloud Key/Everflowing Chalice/Mana Crypt/Mana Vault/Mox Opal/Semblance Anvil/Sol Ring/Thran Dynamo

It's technically a 4 piece combo but there's so much synergy that the 4th piece can be almost anything. It's really fun though, I did a write up about it in my deck description if you're interested: Artifacts Inkarnate

Semblance Anvil or Cloud Key might work better than Jhoira's Familiar, both are cheaper and Kozilek's the only historic non-artifact in the deck that the familiar helps.

Don't feel obligated to respond, this is kind of unreasonable and unrelated.

Do you believe that this deck can work on a hardcore budget?(under $100) I initially thought that most of its 'core' cards aren't super expensive, and i was interested in building this. after looking at the more costly cards, it looks like most of the extra money is in tutors and the manabase - do you think it can be done? or does the combo need those cheap cards so badly? This is what I have so far:

Yawgmoth's Will -> Recoup --- Fork -> Mana Geyser --- Entomb -> Demonic Collusion --- Sensei's Divining Top -> Crystal Ball This one is sketchy --- Demonic Tutor -> Tainted Pact --- Vampiric Tutor -> Diabolic Tutor --- Serra Ascendant -> Sphinx-Bone Wand --- Phyrexian Arena -> Ambition's Cost ---- Austere Command -> Planar Cleansing --- Necropotence -> Painful Truths --- Cloud Key -> primal amulet --- Lotus Petal -> Pentad Prism --- Tithe -> Terrarion --- Abeyance -> Niveous Wisps ---

Consider running Lightning Greaves over Mask of Avacyn if you are just looking for the protection effect the only downside I could see would be if you needed to equip another equipment to the card it was on but I think the mana advantage you get outweighs that.

Not sure how you feel about Mycosynth Lattice but it could be a good addition.

Mana Vault and Voltaic Key could also be good additions aswell as Semblance Anvil and Cloud Key

I like and plan on getting a Helm of Awakening, and I do also like Cloud Key. with my additions of more 0-1 drop artifacts, Trinket Mage will more than likely be seeing play here as well. Spellseeker would be good as well, and i agree with most of the cards you suggested to take out, such as Mind Over Matter, Mirrorworks, and Search for Azcanta  Flip, and possibly the Peregrine Drake/Deadeye Navigator combo. Diabolic Tutor has won me games plenty of times, so I think it's worth keeping in, personally. Thank you all for the recommendations! oh yes, can't forget about Strionic Resonator. ;)

ps: i have just added in City of Brass, which was supposed to be on the list to begin with; i had forgotten i traded someone online for it, and it arrived today!
