And after this nerf, it's still much better than Surging Tempest.

• Virtual Reality Project: Puting on some goggles that let you see stuff that isn't there really fits Demon Hunter, and the artwork just improves this feeling. The effect feels more in-line with Augmented Reality than with Virtual Reality, though.
• Binding Dependencies: A software dependency is when a module of your program requires another module or external code to function. Remeber when you needed to install a plugin to play Flash video games? Well, it's something like that.
• Pesky Bug: A hero having Attack during their opponent's turn? Hearthstone must be bugged!

• Omega Harvester: This one hasn't much going on. Heh.
• Ecosearch: A reference to Ecosia, the search engine that plants trees.
• Slithering Python: The name is a reference to the programming language Python, whose name was in turn a reference to Monty Python. The effect, however, is based on the fact that snakes eat their prey whole.

• I-l0v3-U Bot: A reference to a famous malware called ILOVEYOU, whose effect on your computer wasn't very loving. Just like this little bastard's effect on your opponent's face. 
• Creepy Webcrawler: Web crawelers are bots that index the Internet, making search engines faster and more effective.
• Omega Blaster: Another one that isn't based on anything in particular. It's the last one, I promise.

• Knowledge Analytics: Refers to the process of extracting meaningful knowledge out of raw data.
• Big Datamental: A reference to big data. I thought Secrets fit with the loads-of-information theme.
• Firewall: Firewalls are systems that control traffic going inside a network or a computer. I like how the effect makes sense for the computing thing and for a literal wall made of fire.

• A.I. Project: In real life, most Artificial Intelligence isn't related with actual robots, but in fiction it usually is.
• Cybernetic Crusader: The name is a small reference to Internet activism.
• Turing Test: The Turing Test tries to discern if an agent is an actual person or an A.I. This card makes something if it detects the minion is a Mech.

• Glitchfiend: A glitch is a short-lived error. Just like this card, which makes your HP do the opposite thing for one use.
• Man in the Middle: MitM is a type of cyberattack in which a malicious agent reads the messages exchanged between two other agents, typically, a client and a server.
• Neural Network: In computing, neural networks are a very complex form of machine learning, which has proven to be one of the most effective. For more information about machine learning, check Warrior :)

• Cybercoin: A reference to cryptocurrency and its high price volatibility. Don't invest on cryptos, kids.
• Deep Web Pirate: Just a regular Internet pirate that downloads stuff for free. The Deep Web thing is just to make it sound better.
• Cracker Captain Ada: A very good cracker can steal important information (in this case, Legendary spells). Her name is a reference to Ada Lovelace, considered the first programmer in history.

• Electronics Project: Electronics are the basis of computers. You know, ones and zeros and all that stuff.
• Divide and Conquer: An algorithmic strategy that breaks a complex problem into simpler parts to solve it.
• Mosfet the Flux Twister: His name references the MOSFET transistors, which have been used to develop some types of electronic circuits.

• Background Daemon: Daemons are background processes that execute stuff without you noticing. Funnily enough, Daemon and Demon aren't the same, but since most people confuse them, I gave it to Warlock. Oh, and if you didn't notice, this guy is an Imp.
• Trojansteed: A trojan horse is a type of malware that hides inside a legitimate progam. Like when you download Shrek from the Internet and it steals your bank account. This pesky steed hides inside the card your opponent drew.
• Re-curse-ion: In programming and mathematics, recursion refers to a function that uses itself in its definition. As in the Fibonacci sequence being defined as fib(x) = fib(x-1) + fib(x-2).

• Ping of Death: A very old cyberattack in which a very big message was sent into the network, collapsing it. The effect is just a pun on the fact that 1 damage effects are usually refered to as pings.
• Unbearable Spambot: Spambots are programs that send spam. Quite straightforward.
• Learning Machine: A pun on machine learning, a field of Artificial Intelligence in which programs refine their behaviour as time goes on. Like the YouTube algorithm learning your tastes or Google Translate making better translations over the time.

• Quantum Processor: Quantum Computing is a mostly theoretic field of computer science which uses the wacky laws of quantum physics to work. The advances in this have been very modest so far.
• Cryptographer: Cryptography is a field of computing which makes information harder to decode for malicious agents.
• Omega Android: Its name slightly references Android, the mobile O.S.
• Deidos, the Saboteur: A reference to DoS and DDoS cyberattacks, which disable internet services by overloading them with messages.
• Kernelmeister Ingrid: Kernel is the German word for core. In computing, it refers to the core of the operating system.

Demon Hunter

• Virtual Reality Project now costs 1, down from 2.

Hunter

• I-l0v3-U Bot is now Magnetic and triggers the Goblin Bomb's Deathrattle (instead of dealing 2 damage by itself).

Mage

• Mass Knowledge is now called Knowledge Analystics.

Shaman

• Electronics Project now costs 1, down from 3. Its wording has also been changed.
• Mosfet the Flux Master is now a 4/4 whose Battlecry deals 2 damage per shot. Previously, it was a 3/3 that dealt 3 damage per shot.

Warlock

• Background Daemon is now a 1 Mana 2/1, down from a 2 Mana 2/2. Warlock already has too many 2 Mana Demons in Boomsday.
• Re-curse-ion has had its artwork changed. The previous one looked too much like an anti-semitic caricature.

Neutral

• Omega Android is now a 5 Mana 6/8, up from a 4 Mana 4/6.
• Deidos, the Saboteur is now a 3/2, instead of a 2/3. Also, his Battlecry affects both players in their respective next turns, instead of just the opponent.
• Reality Augmenter Mimi is now a 2 Mana 2/3, down from a 5 Mana 5/6. Also, her name has been changed to Kernelmeister Ingrid.

Cards outside the set

• Tunnel Trogg now reads "Whenever you Overload, gain +1 Attack." Previously, it read "Whenever you Overload, gain +1 Attack per locked Mana Crystal."
