[details=Spoiler]These will be in a random order so be forewarned.
Unstable Portal - Looks like a very neat, fun card. However it seems pretty bad, especially since it’s Mage exclusive. Other cards do this better though the fun of Turn 4 Ragnaros (an extreme longshot) can’t be ignored.
Madder Bomber - Card seems ridiculous in Druid and Mage because of the 1 Damage Hero Ability (not so much in Paladin, you’ll probably kill your own guys just as often). 5/4 on 5 aren’t bad stats either. It’s at its best on a lean board so the blasts are more focused. Could be very good.
Velen’s Chosen - I’m not sure how I feel about this yet. It’s basically a Priest Specific Blessing of Kings, only a turn early with Spell Damage. The Spell Damage isn’t very helpful though when Holy Nova is the only thing that it really helps (Holy Smite…not exactly helpful at the point you drop this). Idk if Holy Nova itself is worth this card. Good to give some extra Health beef but…again, idk how to feel about it or where I would even make room. But to me the Spell Damage is irrelevant.
Cogmaster - Bad card. 3/2 at best and that’s only when you have board presence which is usually the opposite of what you want from a 1 drop.
Dr. Boom - Now HERE’S a great Legendary. Boom Bots themselves are solid, and 7 for 7/7 is average enough. But a 7/7 that can do crazy damage can’t be ignored. Pretty much removes the possibility of AoE against you unless the opponent is suicidal.
Annoy-o-Tron - A very hyped card and understandably why. You can consider it as one of two things. Sunwalker on 2, or Goldshire with Divine Shield. The question will be if the Divine Shield will be worth playing essentially a more expensive Goldshire. Honestly…not sure if it is worth it. Way too easy to break the Shield, especially in 1 Damage HA classes and even if you have to break it with other things that 1 damage isn’t exactly going to punish you. I think the hype will die down on this card quickly. I’d rather play Unstable Ghoul at Turn 2 for Taunt.
Explosive Sheep - Ignoring the awesomeness of a goddamn exploding sheep bot aside…potential shenanigans here. Mage can especially abuse this during the late game as with this they’d have their own 4 mana Consecration…though they’d hit themselves. Potential here.
Piloted Sky Golem - Another fun card. Really understated but who knows what it could get. There aren’t too many terrible Turn 4s. Imagine this turning into a Yeti. Not exactly a constructed card, but a fun Arena card.
Enhance-o Mechano - I’m in love with this card. Really bad stats for its turn but the potential craziness can’t be ignored. If you keep a board, this could be a finisher in its own right. Of course, without a serious board he’s really bad. I just want to see the Enhance dream with this.
Shrinkmaster - I honestly do not like this card. I mean it’s a Turn 2 3/2 which is always nice but the effect is not a Turn 2 one and it isn’t very good at that. Not a fan, especially since it seems it’s Priest Specific. It’s only there for Shadow Word: Pain. Maybe if the drop was permanent or something I’d like it more but since you can’t guarantee the SWP…just meh.
Mimiron’s Head/V-07-TR-0N - We have fucking Voltron. And it’s potential 16 Damage to the face ON TURN 5! That’s utterly obscene. I just wonder if they’ll make Voltron a separate card or not as well. I’m going to assume no because…that shit is ridiculous. Making ALL the Voltron decks!
Tinkertown Technician - Pretty good. Vanilla 3/3 on 3 at worst which isn’t awful. At best, which isn’t hard to do, Turn 3 4/4 and you get a free card. Most of the spare parts are somewhat meh but Reversing Switch is shenanigans.
Blingtron 3000 - Ignoring there’s a card called Blingtron, meh card. Imagine the horror of you getting Light of Justice and the opponent getting Death’s Bite or worse. Understated too. Fun though.
Bomb Lobber - Obscene. Yeah, stats are bad for it’s turn but 4 damage on a random enemy minion? I’ll take that shit all day.
Bouncing Blade - Seems crazy. At worst, 3 mana 1 damage…so you know, don’t do it to a board with a 1 Health Minion in it. God forbid the opponent only has one minion out and it has high health. The 3 mana Ragnaros kills! Will have to see how it plays out.
Clockwork Giant - A worse Mountain Giant. I can only see this being good in the mirror match.
Clockwork Gnome - Bad. The Spare Part cards aren’t worth the bad 1 Drop.
Flamecannon - Another Mage Exclusive and…woo. 4 Damage on Turn 2. That’s crazy. Not great on big boards but on lean boards this card is very strong. Is the one extra damage enough to seat Frostbolt though? Not sure, just because Frostbolt freezes and HA can make up the difference the next turn. Will have to see.
Gnomish Experimenter - …Bad. Overcosted and the effect is meh. Imagine drawing your Legendary and it turns into a Chicken. Just no.
Goblin Blastmage - Mage Exclusive, and really good at that. A Controlled Bomber with good stats. Hard to go wrong.
Mechwarper - Not bad. Stats are average enough for the turn, effect is…meh. Not terrible, not great.
Mekgineer Thermaplugg - Bad unless you can guarantee a ton of enemy deaths.
Micro Machine - Fucking AWFUL. It takes two extra turns just to turn into an average 3/2. Just…no, hell no. Play Shade of Naxxramas, that card’s actually good. This isn’t.
Piloted Shredder - Same as the Sky Golem, only 2 Drops have much worse minions on average (and just way more in general than 4).
Recombobulator - Uh…again, mostly a fun card. Makes me wonder if it could have Wisp synergy though.
Sneed’s Old Shredder - Like the Piloted Cards but you get legendaries. Legendaries are a lot tighter in number and tend to be solid on average. Seems good.
Spider Tank - Fucking FINALLY. One of the most hype cards in the set and it’s a Vanilla. Why the hype? We FINALLY got the Neutral Turn 3 3/4 we wanted. And it’s a Mech at that which is actually really damn helpful due to this set. Play it in everything (maybe not everything…but so good).
Upgraded Repair Bot - Another Priest Specific and holy damn its good. If the opponent didn’t take care of that Lightspawn last turn…he ain’t going to do it now. Just good in general.
EDIT: Never mind, Repair Bot only gives Health to mechs (makes sense). Card is very meh instead.
