Ehh, well, for one thing these are commons and grim tutor is not. Also, this is uncounterable, whereas grim tutor is not. The life thing is kind of neat. One of the points that I am asking is why is grim tutor better than this? it's versatility? as in, what, you can fetch a grand total of 2, maybe three cards that this can't.(desire, bargain, jar)
I don't honestly know, this is just an idea, is it bad? probably, is there something better? probably, does it need to be considered? yes.
I also mentioned that his probably wasn't the right place for this card. I really think hulk or maybe doomsday could benefit from the uncounterability of this card best.
Hmm, Hulk? it can get deed, tog, intuition, cunning wish, will...that's an idea.

So, as I was going through ravnica cards I noticed something that seemed rather good. The name of the card is Dimir Machinations and is useless in itself(some random library manip I think). This was one of the three cards that met my specifications of being a three casting cost card with transmute. This is the one that was castable of a dark ritual. So, did Grim tutor just get printed several months early and without the annoying life loss or rarity? Maybe. The restrictions on casting cost are annoying to say the least, but it is uncounterable(which is some good?) Also, with deathlong the draw sevens are a three casting cost, as is will, so there isn't much you can't go for with this(the two notable exceptions being tendrils and Desire)
as such I began thinking of a deck to play at a tournament in a few weeks, and this is what I came up with

//land(10)

2''
//artifact acceleration(13)
5 powermox
1 Black Lotus
1 Lotus Petal
1 Chrome Mox
1 Mox Diamond
1 Mana Crypt
1 Sol Ring
1 Mana Vault
1 Lions Eye Diamond
//Other acceleration(7)
4 Dark Ritual
3/2 Cabal Ritual
2/3 Elvish Spirit Guide
//30 acceleration/mana

//Tutor(7)
4 Dimir Machinations
1 Mystical Tutor
1 Vampiric Tutor
1 Demonic Tutor
//Draw Sevens(4)
1 Timetwister
1 Wheel of fortune
1 Tinker
1 Memory Jar
//b|20|<3|\|  (4)
1 Yawgmoth's Will
1 Minds Desire
1 Necropotence
1 Yawgmoth's Bargain
//Protection(6)
4 Duress
1 Hurkyls Recall
1 3cc Disenchant
//Consistency(5)
4 Brainstorm
1 Ancestral Recall
//Kill(2)
2 Tendrils of Agony

Card Choices
Lands- the 5c lands were best for old Death long since the deck really was 5 colors. This deck may prefer/handle something a little more elegant(i.e. dual lands).
Artifact acceleration- should look pretty ordinary, with the excpetion of no Tolarian Academy. This is because I don't think I have th room for a crop rotation, and since this deck is designed to go off in the first three turns, I don't like the total randomness of it.
Other acceleration- ESG's and Cabals, these may be bad or good, I don't honestly know. I think some combination may be necessary since the deck needs to have more rituals for Dimir machinations, and the Green is really useful for a 3cc naturalize(there's one in Ravnica).
Tutor- nothing much to say here other than "why no consultation" that would be because it was the weakest of the tutors, if someone with more experience than me tells me "play it or the deck is bad" I'll cut something for it, otherwise, I really personally hate it.
Draw sevens- no windfall, the classically worst draw seven. Didn't really have room for it is all.
Broken- The 1337 part of the deck. Random insanely powerful cards that you can go for and just win. Again this is really ordinary, the ability to just draw a Yawgmoth's will would be awesome
Protection- I really like hurkyl's recall, although I know that this really should be a chain of vapor. The 3cc Naturalize is there because I can easily fetch it and cast it.
Consistency- Nothing out of order here, no walk because I didn't really have room for it
Kill-2 tendrils, I might need more than one for some reason(duress or such) but I really would like to find a three casting cost win. A brain freeze over the second Tendrils may be in order so we can fear no cranial extraction.

That's about it. I am not convinced that this is the right way to break Machinations, I think Hulk or TPS may be better, this is simply what I have some experience with.
