Would the wording not be more like:
If you didn't play ~this~ from your hand, sacrifice it.

Does artifact "washed" mana count or does it have to be a  add effect?

Think of this in a game where you manage to get it to stick on turn 6 or so. You have 6 or 7 other permanents, you opponent has about the same and you have 40 or so other face up cards, that's a pretty full table. How do you stack your deck? Where is the top if all the cards are face up? If you just flip over your deck, it's not technically revealled. What happens when your opponent disenchants your dream?

What happens in your draw step (or any other draw effect for that matter)? Which card do you draw? Your top card, the one you would draw next, is on the bottom (or randomly revealled).

What happens when someone mills you. Which cards do you mill?

Hum, they were my first impressions.

@zimagic
Addressing your two main points:

As worded, "washed" mana would be acceptable because it is generated by a mana ability of an artifact.  So Gemstone Array or a Chromatic Sphere-type effect would work fine.

Secondly, regarding library order, according to this article, any randomized pile of cards is treated as having no order under current philosophy.  Therefore, barring Scry, Vampiric Tutor, or a similar effect, you would be able to just flip over the library when this card came into play.  You are correct, however, that it needs another clause requiring a shuffle if it ever leaves play.  The problem of Opalescence + Humility, where this never leaves play but the library is no longer revealed, is somewhat stickier.  I can't recall any past templating to the effect of "When this ability is no longer in effect, shuffle your library."

As to your "played from your hand" clause, that would allow a Solidarity shell to... I don't know, like flip it off Mind's Desire and then win at instant speed (presumably without Reset... so not very good).  EKM's language doesn't really work properly either, though, since it still allows Academy Rector and friends to function.  It really needs something more like Phyrexian Dreadnought, so it says, "If ~this~ would come into play, if you played it from your hand, put it into play.  Otherwise, remove it from the game."

All of this having been said, "Planeswalker Enchantment" ?  To my knowledge, we have no earthly idea what a "Planeswalker" card is or what it does.  It's possible that it will have special rules baggage like Tribal does.  This card may be wholly inappropriate to the type.  Do you have some kind of secret FAQ I don't know about which offers insight on this matter?

[EKM_Ichorid]

I just called it a Legendary Planeswalker Enchantment to be cool. I can take it out.

As for playing with it revealed, I wanted to be able to keep it in the same order. How would I word that?

Right now, the wording could be:

Urza's Dream       
Legendary Enchantment
You may only use mana produced by artifacts to play Urza's Dream.
When Urza's Dream comes into play, if it was not played from your hand, remove Urza's Dream from the game.
Play with your library revealed.
You may play cards in your library as if they are in your hand.
When Urza's Dream leaves play, you lose the game.
As Natzre entered the planeswalker's dream, he was overwhelmed with the brilliance that was Urza.

It really shouldn't leave play when you can use your whole deck, but if it does, you lose. Solves some problems.

About milling, I have no idea. I would want the library to be like the graveyard...it stays in order yet it is revealed to everyone. That way you would draw in the proper order and mill in the proper order.

[zimagic]

You could try and make it a little more simple. Instead of flipping your library, say: If you would draw a card you may search your library for a card instead and remove it from the game face up. You may play that card as if it was in your hand.

You'll lose unplayed cards if the Dream leaves play or keep the lose the game effect. You can draw as usual or tutor for whatever you need but you need to trigger a draw to do so. [Though as I type I realise this is just a degenerate DT though the original versions is essentially a "you've already drawn your library, what broken stuff can you do now?" effect.....] You still get the "whatever you need from the library effect".

~This~ can only be played from your hand.

Use only artifact mana to play this.

When ~this~ comes into play, place your library in your hand.

Play with your hand revealed.

If you would draw a card, skip that draw instead.

You have no maximum hand size.

And don't forget the played from hand limtation.

Nice read, vartemis.

What about that instead? Sideboard/RFG instead of library...

[Ephraim]

I am extremely cautious about this card.  Even the most casual player can orchestrate an instant with with exactly the 30 (or even 15) cards that he or she wants.  I am basically of the mind that no matter what restrictions you put on this card, as long as it allows you to play cards from your library or sideboard as through they were in your hand, then it basically reads, ": You win the game."

Your solution, by the way, EKM_Ichorid, leaves an instant-speed window during which somebody could play 4 Dark Ritual, 4 Cabal Ritual, Vampiric Tutor (for Tendrils of Agony), and any instant black cantrip they want to win the game.  I'm not saying this would bust open Vintage.  I'm just highlighting that if you wanted to cheat this into play with Academy Rector, you could still win with it.  Nor am I saying that everybody using this card would automatically build an instant-win Dreamboard -- just that it is trivially easy to create such a board.

[Norm4eva]

Even with the 'artifact mana only' restriction, I have some of the same qualms as Eph.
What if it revealed a set number of library cards, like the top 7 or whatever.

I agree that this is an enchantment that says "You win the game."  Whatever goofy restriction is put on how you can play this, the actual play cost of this in Eternal formats is "Kill my Rector" or "Replenish".  Meanwhile, with the "Use only artifact mana" restriction, this card is basically unplayable in almost any potential Standard format.

[Ephraim]

I suppose you could always use a clause like, "If Urza's Dream would come into play, if you did not play it from your hand, shuffle it into its owner's library instead."  At this point, though, it just feels like we're making silly limitations to justify an ability that is grossly overpowered.

[Matt]

Do you really need to be able to play ALL your cards? Why not just artifacts (Urza's specialty)?

[vartemis]

Do you really need to be able to play ALL your cards? Why not just artifacts (Urza's specialty)?

so when it comes into play, search your library for any number of artifact cards and remove them from the game.  Until end of game, you may play those artifacts as if they were in your hand.

that sound about right?

[Matt]

Something like that, yeah. Maybe make it "until the end of your next turn" so you have a chance to untap and cast stuff, otherwise this will just dump Moxes and stuff.

[zimagic]

[Though as I type I realise this is just a degenerate DT though the original versions is essentially a "you've already drawn your library, what broken stuff can you do now?" effect.....]

So what's the aim of the card? I understand it as an unlimited access to your library. Is this even an effect we want whatever the restriction?

It's like YawgWill for libraries, isn't it?

So if we're going to make it, why not make it a sorcery, keep it within the turn and restrict the number and/or types of cards you can search for as has been suggested by Matt & vartemis?

Fixed quote tag. -Matt

[EKM_Ichorid]

In the newest version, it can't be cheated into play without an instant speed win. I'll make sure to post it on the top post so everyone can see it. Because it can't be cheated, it's not insane. It's hard to cast and I think I'm going to change the wording to "remove it from the game INSTEAD". That closes the window.

[Anusien]

I think all the clunky limitations junk up the card.  You can simplify them with, "If this comes into play, if you did not pay its mana cost with mana produced by an artifact, sacrifice it."  I'd also remove the Legendary, although it is flavorful.
I have to admit, I don't like either current wording.  Neither fit Urza.  What do RFG cards have to do with Urza.

RFG = Creating new things never seen or thought of before. They're "outside the game". I always thought of sideboards as the planeswalkers developing new spells and machines to defeat the opponnet.

Your wording is so simple, I never thought of that.
