[This review considers flavor only. If you don't care about the fluff, feel free to slide right past it.]
Let's have a look at the flavor, uh, text.
The way it is written might be a direct reference to a certain science fiction novel, and a single work of fiction I have found to be the most disturbing thing I have ever read - that is, "I Have No Mouth, And I Must Scream".
To those unfamiliar with the topic, it's a postapocalyptic sf story describing a cold war-era military computer (known simply as AM, for Allied Mastermind) gone rogue, taking control of the whole world's nuclear arsenal and almost completely wiping the humanity off the surface of Earth. Almost, because there have been five people left - which AM had purposefully kept alive and made almost completely immortal, for the sake of torturing the living heck out of them for the rest of eternity with the most cruel ways imaginable - out of sheer contempt and hatred for creating it, but making it non-sapient, unable to express creativity, unable to touch, taste, breathe.
There are only two parts in the novel in which AM "communicates". It uses the telegraphic Baudot code - the dots in five rows, punched onto a nylon tape - to say "I think, therefore I AM" and "cogito ergo sum", the sign of it being self-aware and the proof that everything it did, it did because it WILLED to do it.
What is the reference? Unsurprisingly, the Baudot code is the alphabet this flavor text has been presented in. The dots herein add up to words "The Destroyer of Worlds". Not very imaginative for a card named "Apocalypse", right? Not really. Harbinger's flavor text, shown in the same manner, transcribes as "I Am Become Death". The two add together to form a well-known quote from Bhagavad Gita, made popular by Julius Robert Oppenheimer, a man most known for his part in Manhattan Project, and the father of the nuke.
Think again. Apex is said to be a military AI, used for some nefarious purposes before the great Blackout (which had obliterated the Internet as we know it today, promptly replaced with SYNC, or simply "the Network"). The Blackout itself is said to have been caused by an unknown, self-aware worm able to evolve so rapidly that any effort to stop it would be completely fruitless. Could that be Apex? And if so, could Apex do it again?
Would it do it again not out of so-called notion of hunger, but because it hates its creators and wishes to destroy them?
