First, I love this card.
Second, we seem to be confused about what Entropy means. Entropy is not necessarily randomness, and is more aligned with things becoming uniform. Statistical entropy is more aligned with decay and the Greek roots of the word is more fascinating by far.
It is derived from the two Greek words en (meaning "in") and trope (meaning "turning"). The concept is of something spiraling inward upon itself.
Not to take any of the fun away, but iI think cards that are currently in the aether element (the cards that make copies of other cards and such) should be in entropy and the random-type cards in entropy would fit better in aether. Just my opinion.
