Do you think that using Ghostly Prison would make this even more annoyingly controlling? Having all those weak creatures instead of enchantments would be bad enough for opponents, but having to pay 2 for every one of those they tried to attack with would be so over the top. Soul's Attendant could be good too, for the life each time a creature enters the battlefield, if you think this deck could use a little lifegain.

I'm not too familiar with Infect cards, so I may not be able to find much, if anything, that helps, but I'll try and come up with something at least. I'll probably learn a few things myself from looking it over.

That looks somewhat tough. Have you thought about adding an Azusa, Lost but Seeking? It does let you play three lands per turn, after all.

So, how reliably does this deck pull through for you and win? I'm curious about that, because even a relative greenhorn such as myself has heard that five-color decks are tricky to pull off for anyone but a professional. If you are such a professional, congratulations, and I would be happy if you felt like taking a look through my own 5-color deck idea, titled "Golden Power", and letting me know what you think.

I'm not certain what this deck's strategy is at first glance, other than to win, but I have a couple of cards that might go nicely with all your Artifacts.
Golem Artisan for powerups,
Darksteel Juggernaut for more power from more artifacts,
Galvanic Blast- may be better in this deck than Lightning Bolt
Rusted Relic (maybe)
Great Furnace, to help with Metalcraft abilities,
Tuktuk the Explorer... I'm not entirely sure why, but it seems handy.
Lightning Greaves, to give Shroud and Haste, thereby powering up whatever you want
Valakut, the Molten Pinnacle, for damage, and
Quest for Pure Flame, for sheer damage.
I'm aware that that's a lot of cards, but hopefully something in there will be helpful.
As long as you can decide on a strategy for your deck and make sure to add cards that can effectively represent that strategy, you should be good to go. And if this is a burn deck, I'd also suggest Red Sun's Zenith. Thank you for reading through the longest post I've ever written, and good luck building your deck.

Thanks for your ringing endorsement of my deck. It's only beaten yours once, that I remember. I credit your years more experience than mine, the efficiency of mono decks, and this one in particular. Honestly, great design here. Be proud- you're the reason I don't feel safe without Eldrazi around.

Hope I can figure out something useful to help, then.

Omnath, Locus Of Mana would be insane to add to this deck. Just think how much mana you'd have to throw around!

Even better than Diabolic Tutor for green decks: Chord of Calling. It's a godsend for anyone who owns an Emrakul. If it wasn't obvious from the fact that I spend time thinking about ways to use a card like that, I'm a fan of Eldrazi cards.

Nice. All I can think of other than Omnath, Locus of Mana, to help build up your mana pool, and maybe Doubling Cube, is Chord Of Calling, which is my personal favorite way to summon Emrakul in a mono-green deck. For any ideas other than that, you'll have to take a look through my Green Meanies deck, which is basically an elf deck customized for using Eldrazi.

Looks good, although Light From Within is a pretty nice card for mono-white decks.

Nice deck, in my opinion. Wonder what sort of hell this deck would unleash with Idyllic Tutor to call Sanguine Bond whenever it's needed, or Cradle of Vitality, to pump up Lifelink creatures even more and let them feed off of their own might for even more power? (Wow. I really have to get my hands on one for myself and try that idea now.)

I'll see what I can come up with, then. If I think of anything good, I'll post it on the deck's comments section.

Sorry- Just had one more thought- Maybe Angelic Arbiter, or Aura of Silence. That's all, for real this time. Good luck.

I'm more of a burn deck specialist, but of the white cards I've seen, I think that Ghostly Prison may be right up your alley. Its effect even fits with your deck's title.
And also, Idyllic Tutor might be a handy thing to have around to help you get enchantments when you need them. That's all I can think of for now, but hopefully you'll find one of these cards helpful.

Thank you for all the help on my Midnight Sun deck, which I am pleased to say has been improved rather a lot from your input. In fact, in the last game I played, I was at 300-something life. There's almost no point in keeping track at that height.
On another note, Midnight Sun has made it onto the "Upcoming" page now, so I'll take that as an indication that it's safe for me to give suggestions for black/white decks.
So I finally might be able to help out a little here.

Gimme half a month, and I promise it'll be somewhat more difficult for you to stay at 4,000,000 life again.

Thanks. I'll put in the Celestial Mantle right now, and I ought to be able to find a Felidar Sovreign in a few weeks. Finally, my first draft of this deck is almost completely within my reach. It's been pretty quick considering I just learned about this game in mid-November.

Looks like fun. I'm actually a fan of B/W decks, myself. I use a lifegain/burn one personally. Nice control deck.

Wait, wait- I just thought of another card: Shield of the Oversoul. It's common, but it gives Naya Hushblade lifelink and indestructibility, plus +1/+1 and shroud because it's a multicolored permenant.
Should be fun.
