Such a sad waste of a card. I know it's a decent enough sac engine, but it could've been so much more! Look at the old Mirrodin's Core! This could've been a Phyrexian mana fixer (Something that, as of yet, doesn't exist), taking off of an old card's flavor and twisting it into something interesting, like all good Phyrexianized cards should do!
Take, for example, this version I thought up:
Phyrexia's Core (Uncommon)
Land
: Add 
to your mana pool.
, Sacrifice an artifact: Add one mana of any color to your mana pool.
Same role filled, only now it's an actually decent card simply by itself, and absolutely dripping with flavor, rather than this bland, colorless mess of a card which makes no sense no matter how long I look at it. Why would a land that eats artifacts for Phyrexia give life? Why?

Never underestimate lands with utility. After all Mycosynth Wellspring, Ichor Wellspring, Spine of Ish Sah, and a few others are all willing to give up existance for great Phyrexia.
The point of this card also lies in the fact that it is capable of replacing cards like Throne of Geth if you don't mind missing the proliferate. It just allows you to some cards for other cards and lands like this are quintessencial for the development of new stratagies.

Whenever I see this card, I can't help but be reminded of the beginning of the Transformers Movie (the REAL Transformers movie, not the Bayformer ones) when you see Unicron digesting Lithone and all his systems start powering up. If you remember the movie, you know EXACTLY the frame I am talking about.
I trust that Wizards will do the right thing and give me a card that transforms Mirrodin into a giant robot voiced by Orson Wells.

Right. It's so easy to be blind to the fact that this is clearly a sac engine.
Use it with Modular, or as other people stated, the two wellsprings and the spine. The one life is merely a minor fringe benefit. Maybe even run it next to your Disciple of the Vault(s) as well.
In fact, I might even build a deck with this next to some Clone Shells and Summoner's Eggs with eldrazi/colossi in them.

This may seem underwhelming, but you have to remember just how few artifact sac outlets there are in this block. This card is a godsend in limited and block for everyone running Perilous Myr, Ichor Wellspring, Mycosynth Wellspring, and more. The fact is, if you're running a lot of artifacts like these, you can afford to run a non-coloured land or two, so there's very little downside to throwing this in and giving your wellsprings and Slag Fiends the boost they need. This card may not be spectacular, but it's very, very useful.

Run with Glissa, the Traitor. You can sacrifice the artifact of choice w/o having to spend slots on a crappy sacrifice outlet, or crappy cards (see Horizon SpellBomb) just because of their sacrifice clause. Allowing you to build MUCH better decks, and make Perilous Myr incredibly annoying.

Is it just me or is this land about to go into cardiac arrest?

Kind of odd switch to me.
Mirrodin's Core gave you any color of mana every two turns
Phyrexia's Core destroys artifacts (checks with phyrexia) for life gain (wut)
i know there are plenty of art saccing that could use this, but from a mana fixer to a life gainer.. it just seems off.

I like the art hommage to Mirrodin's Core,
but even though a sacrifice outlet on land is great, i'm not quite content with what it does.
The mana activation cost doesn't seem right.
Overall the ability doesn't seem right compared to Mirrodin's Core. I would have loved the ability to be
", Sacrifice an Artifact: Add one mana of any color to your mana pool."

I'm going to jump on the "don't knock it until you know how to use it" bandwagon here... Life gain, let alone a solitary life seems underwhelming at first glance, but the possibility here is actually much scarier than "1 life every turn", because it's activation ability allows it to be used in response to something else. In an artifact engine, this one life is often what you need to survive a full turn, or push out an off-color Phyrexian mana spell. Ontop of that it's a non-basic utility land that doesn't have any excess conditions for it's usage other than "have lotsa artifacts handy"
