Dazzling Reflection - This is a neat effect, and it seems to be one variant of the "reverse lifelink" idea from earlier in design. To explain, an article mentioned that before they reached the idea of using C costs to represent Kozilek, they investigated having it change keywords to be their opposite.
Expedition Raptor - Wow, this is complete junk. Compare to
Supply-Line Cranes, where you more often put the counter on the creature, and you can't even do that here.
Iona's Blessing - This aura seems very annoying for the enchanted creature. Also, Iona is mentioned but doesn't get a card?
Isolation Zone - I didn't expect to see this effect at common anymore.
Stoneforge Acolyte - Another example of "card draw" in white, though I suppose this is more like a restricted library search.
Wall of Resurgence - This seems really good, getting both a good blocker and an on-cost attacker.
Cultivator Drone - At first, I was wondering why the part about using the mana to "pay a cost that contains C" was included when there are no colored cards that do that, but then I realized that it refers to the triggered abilities you have to pay for.
Slip Through Space - This seems good.
Ancient Crab - I find it amusing that we're following the story of a crab that was just chilling at the Sea Gate and decided to wander elsewhere when it got destroyed.
Roiling Waters - Oh hey, the finally made a "super cantrip". It also has the odd feature that it doesn't get countered if the two creatures become invalid targets, since the player is targeted too.
Essence Depleter - I can't say I'm a fan of these plain flavor texts that just straightforwardly present a story event.
Havoc Sower - I just want to say how it's interesting how a boost of +2/+1 has a specific meaning in Magic, referring to
Unholy Strength.
Kozilek's Translator - I find the name of this creature amusing.
Oblivion Strike - This seems quite good for common removal.
Visions of Brutality - Another example of the "reverse lifelink" from early design.
Grasp of Darkness - I didn't expect to see
this reprint.
Tar Snare - Rather odd that we have this in the same set as Grasp of Darkness.
Untamed Hunger - This is definitely a card designed to be reprinted. Also, another example of an Unholy Strength callback.
Consuming Sinkhole - I think you guys are underestimating this in Limited, though it's still definitely a sideboard card. It's an interesting design.
Immobilizer Eldrazi - This is a neat effect. I guess the flavor is that it's making everyone's butts too heavy.
Devour in Flames - Maaaybe playable in Standard? Also, this is the first uncommon card to reference planeswalkers, I believe.
Kazuul's Toll Collector - Hey, they remembered that red can attach equipment for free sometimes! Also, another old character being referenced who doesn't get a card.
Press into Service - I'm surprised we're getting another Act of Treason effect in a small set.
Tears of Valakut - Valakut and the Sea Gate were an OTP. Who knew? Anyway, I don't think there are enough big flying creatures in Limited or Constructed for this to see play. Maybe after rotation?
Elemental Uprising - The wording here is interesting, in that the "must block" aspect is clearly there just to remind the player that you can use this to block. EDIT: Derp, it says it "must be blocked", not "must block".
Harvester Troll - Sacrifice something to turn a 2/3 for 4 into a 4/5? How about no.
Natural State - Could see Modern play?
Nissa's Judgment - It looks like green can have its creatures deal direct damage to creatures without fighting after all.
Captain's Claws - Seems like a good equipment card.
General comments:
* Support looks like junk.
* Cohort seems dull, but it might help in grindy matches.
* I'm really surprised that red didn't get any ritual effects, and that green didn't get any mana producers besides Scions.
* Green still looks pretty bad for Limited.
* The equipment available doesn't seem worth using the equipment-matters cards.
EDIT:
And chump. It's really important.
edit: I'm getting the feeling from MaRo's replies on twitter that something else was going on behind the scenes besides the 2-block change
edit2: confirmed, something big went down that isn't public yet.
Since you guys never link things,

Big change in how they made Magic
