It's a 2-mana Tutor. If you don't rate this above at least 3.5 stars, you know nothing about Magic.
Over 4.5 might be a bit extreme (after all, it's not even an instant), but it is a cheap tutor that can fetch you any land you want. Oh, and by the way, all land cards have CMC=0, so in one way, it's better in the decks it goes in than Mytical Tutor because spells do not generally have CMC=0.
While it might 'cost' you your land drop for the turn, you are either going to be ramping your basic lands to cast something really big next turn (I would feel just fine with playing 2 of these on turn four), or you'll be fetching a Ultility Bullet that does something incredibly powerful in your deck.
This is Green's Demonic Tutor. Elvish Tutor.
(errata: does not make you any better at rock n roll than you already were)
(errata 2: apologies for the 'Elvish'-'Elvis' pun. I could not resist.)
I think almighty abacus raises an interesting point- I don't agree that all 5 star cards must be infinit... (see all)

It took me a while to figure out the amazement of this card. I was wondering, "Better rated than Rampant Growth? Why?"
But it's the same reason why Primeval Titan is STILL $15: any land has now become your b**ch, if you pardon my language.
4/5. It's a pretty good fetch-land spell. All I'd really need is some kind of foul Cabal Coffers copy that does the same for green... TOO BAD GREEN DOESN'T HAVE ENOUGH RAMP!

So. . . green got Demonic Tutor? But only for lands? Who cares, some lands are better than most spells anyway. However, I prefer the versatility of Tolaria West.

I didn't realize so many people were so one-track that they read this as "get a Tolarian Academy/Gaia's Cradle/Serra's Sanctum". But, power-lands are what they are I guess; I'll never see why this could be better than Crop Rotation, as you can drop it first-turn AND have your land already in-play, untapped, that turn.
I guess, all the commotion over this card, means there probably ISNT a 
for a 'any land from your deck into play tapped' card yet. Even if it said non-legendary to keep it from wrecking Legacy or something; I figure those formats are hell enough anyway.

Grove of the Guardian, Gavony Township, Gaea's Cradle, Kor Haven, Winding Canyons etc. etc...
So many important lands I can tutor for with this, in my Trostani deck... And they may not really look like this, but some lands really can win you games, if played in the right situation (guess it really makes some sense that they b& Primeval Titan in EDH). I think, this really is an awesome card. The artwork is just magnificently beautiful too.

Whats the most expensive part about building a competitive deck? You dual filled land base of course, this will let you pull anything you want. and its splashable.

I've been wondering about a card like this, now I've found it. Yes sir, I'll take my Dark Depths with a side of Vampire Hexmage.

This card is, for me, equal to Rampant Growth. The choice will depend of the deck you build.
In a deck where lands are your keycard, this card will be more efficient than Rampant Growth. If you have Urza's Mine and Urza's Powerplant on the battlefield, tutoring Urza's Tower may give to you a serious advantage over your opponent.
Otherwise, if you have more basic lands and if your nonbasic lands are less important, Rampant Growth will do a great job.

In terms of the 2 mana rampers, it's hard to say one is strictly better than the others. There are likely to be situations where one of them performs its intended role better. However, Sylvan Scrying is a darn good card. There are many powerful non-basic lands that can be used, and having them just in your hand (compared to on the field) is a smile price to pay. Gaea's Cradle, Yavimaya Hollow, Urborg, Urzatron, Valakut... nomnomnom.
I already run Expedition Map in most of my Bx decks (for Cabal Coffers + Urborg engine)... could easily see myself running these in a lot of Gx decks thanks to Cradle and Hollow.
