Ok, there are set reviews, I'm going to be referencing several:
LSV's from Channel Fireball
http://www.channelfireball.com/articles/dragons-maze-set-review-white-azorius-and-orzhov/This guys' set review
https://mtgshops.com/posts/dragons-maze-limited-set-review/87This site's set review, which I hope is all written by one person
http://thoughtscour.com/category/set-review/I will be sorting them by LSV, because he's LSV and has actual cred, unlike the other people I don't recognize
WHITE
Scion of Vitu-Ghazi
LSV: 4.5
DO: 4.5
TS Sealed: 4.0
TS Draft: 4.0
First pick rare bomb, everyone agrees. This might be a little worse in triple DGM than people are projecting for DGM/GTC/RTR because there aren't very many creature tokens better than a 1/1 bird outside of rare/mythic. (Trostani's summoner makes 4/4 tokens, those are pretty cool, and Alive is a 3/3 token, but that's about it).
Haazda Snare Squad
LSV: 3.5
DO: 3.0
TS sealed: 2.5
TS draft: 2.5
LSV rates this card pretty high compared to everyone else; something to keep an eye on. It's a good 3 drop, and there aren't a lot of those.
Renounce the Guilds
LSV: 3.5
DO: 2.5
TS sealed: 1.5
TS draft: 1.5
Multicolour cards are more frequently bombs--unlike sac effects this will almost always hit something big which is why LSV rates this highly. But a lot of other people seem skeptical about this, which means people might underrate it?
Sunspire Gatekeeper
LSV: 3.0
DO: 3.0
TS Sealed: 3.0 (2.0 without 3 gates)
TS Draft: 3.0
Across the board pretty much total agreement on this one. LSV also notes that it's worth running off-colour gates once you have about two gatekeepers.
Boros Mastiff
LSV: 3.0
DO: 3.0
TS sealed: 2.0
TS draft: 2.5
Bear.
Steeple Roc
LSV: 2.5
DO: 2.5
TS sealed: 3.0
TS draft: 2.0
5 mana for a 3 power flier is consensus playable, but also consensus not that great. TS does feel like it's better in slower formats (like sealed) though, so that's something to bear in mind.
Maze Sentinel
LSV: 1.5
DO: 2.5
TS sealed: 2.0
TS draft: 2.0
LSV gives this entire cycle lower than everyone else does, and I think the reason is that having a sensible mana curve is still important in limited, and chances are you're going to have uncommon or rare bombs to stick in the 6 slot.
Riot Control
LSV: 1.5
DO: 0.5
TS sealed: 1.0
TS draft: 1.0
Everyone agrees this is garbage. If people do play a lot of phytoburst, though, this is an obvious board-in.
Wake the Reflections
LSV: 1.5
DO: 2.0
TS Sealed: 1.5
TS Draft: 2.0
I expect this to be total garbage in triple DGM due to a scarcity of token makers. Moreso than it already is.
Lyev Decree
LSV: 1.0
DO: 2.5
TS sealed: 2.0
TS draft: 2.5
LSV rates this a lot lower than the others--which it's a straight up card disadvantage sorcery that pushes a little more damage through; if I'm expecting the format to be slow and about bombs, I should probably think of this like LSV
AZORIOUS
Lavina of the Tenth
LSV: 4.0
DO: 4.5
TS sealed: 4.5
TS draft: 4.0
Yeah, it's a bomb, and obviously so.
Ascended Lawmage
LSV: 3.5
DO: 3.5
TS sealed: 3.5
TS draft: 3.5
Absolute and total consensus on this one. Also noteworthy that Armadillo Cloak is in this set (under a different name, but whatever), and Ascended Lawmage is just about the best thing to cloak up in limited.
Beck//Call
LSV: 3.5
DO: 3.0
TS Sealed: 4.0 (3.0 for just Call, 1.0 for just beck)
TS Draft: 4.0 (3.0, 1.0)
LSV is pretty clear on that he would play this whether or not he even had the mana to fuse it in his deck, and would not expect to fuse it very often at all. He does make the point that 4 1/1 fliers in limited pretty much guarantees card advantage.
Council of the Absolute
LSV: 3.5
DO: 3.0
TS Sealed: 3.0
TS Draft: 3.0
LSV likes this a little more than the others; game one it's ramp that leaves a good body behind. Game 2 you can stop their bomb.
Jelen Sphinx
LSV: 3.5
DO: 4.0
TS sealed: 3.0
TS draft: 3.0
TS does note "I've given it a 3.0, but it might be better than that."
Deputy of Acquittals
LSV: 3.0
DO: 3.5
TS Sealed: 3.0
TS Draft: 2.5
Funnily enough with the same score from LSV as a practically vanilla bear...but costing two specific mana actually does hurt it a lot in the role the bear would fill (being aggressive; this is probably not dropping turn 2).
Protect//Serve
LSV: 3.0
DO: 2.5
TS sealed: 2.0
TS draft: 2.0
It's a combat trick, and one of the only ones in the set, and one that has an outside potential for a 2-for-1. LSV does rate this a little higher than the others, so that's something to pay attention to--it's a card that might come around the table and is worth taking.
Render Silent
LSV: 2.0
DO: 2.0
TS sealed: 2.5
TS draft: 2.5
Cancel according to LSV ranges from 1.5 to 3 depending on the format (the slower and more bomb intensive the format, the better it is, obviously). I should maybe actually edge this up to 2.5-3 range in my evaluations just because of the low amount of removal and high bombiness of the format. I'm not keen on the colour commitment, though.
Restore the Peace
LSV: 1.0
DO: 2.5
TS sealed: 1.0
TS draft: 1.5
Yeah, this is pretty bad, particularly since it bounces your own stuff too if you get into any combat. Although apparently has potential for a few people to overvalue it.
ORZHOV
Blood Baron of Vizkopa
LSV: 4.5
DO: 4.0
TS Sealed: 4.5
TS Draft: 5.0
Obvious bomb
Teysa, Envoy of Ghosts
LSV: 4.5
DO: 4.0
TS sealed: 4.0
TS draft: 4.0
5 turn unblockable clock, and your opponent can't really attack back.
Ready//Willing
LSV: 4.0
DO: 3.0
TS Sealed: 4.5
TS Draft: 4.0
If you cast both sides, you basically win. Interesting that one site would undervalue this slightly, but with 2/3 people noticing how good it is, it's not like I can expect it to go around the table.
Tithe Drinker
LSV: 3.5
DO: 3.5
TS Sealed: 3.0
TS Draft: 3.0
I'm inclined to side a bit more with TS on this one--two drops are going to lower in value, and ones that cost two specific mana are almost never going to drop on turn 2. Extort is still really good, though.
Maw of the Obzedat
LSV: 3.5
DO: 3.0
TS sealed: 2.5
TS draft: 2.5
One of those cards LSV rates more highly than the others, and the reason being he sees it as a nightmare to play against. Which I think is the right way to think about it--if you consider it a proactive card, and start looking for tons 1/1s to sac, you're not going to find any, but as a reactive card that messes with removal and combat, even if you never activate it, makes decisions very hard for the opponent.
Profit//Loss
LSV: 3.0
DO: 3.0
TS sealed: 3.0
TS draft: 3.0
Everyone recognizes this as good but not great in limited. Interesting thing to note: LSV has this at the same score as protect//serve, which feels off to me.
Sin Collector:
LSV: 3.0
DO 3.0
TS sealed: 2.5
TS draft: 2.5
Eh, it will miss a lot, but 2-for-1s seem good if I expect the format to be slow at all, some bombs are spells not creatures, and information is good.
Debt to the deathless
LSV: 2.0
DO: 2.0
TS Sealed: 0.0
TS Draft: 0.0
Bombs will probably finish the game before mana gets this big.
Obzedat's Aid
LSV: 1.5
DO: 2.5
TS Sealed: 2.0
TS draft: 2.0
Yeah, only your graveyard hurts.
Ok, will summarize other colours/guilds later....
