I think I'm generally bad at making a stable argument, so sorry about that.
However, I did read the shape-shifter part and I think that's where Kitsune really fits as
- it's shapshift ability is what allows it escape I suppose and when it upgrades it "evolves" with it's shapeshifting to generate
as well.
The generation of Entropy is special here because this card is "protected" from being killed - as long as you can keep playing the Kitsune (
drawing it is easy w/a few hourglasses) you have a quantum generator that is more durable against destruction (no other generator can currently send itself back to the deck) and can fuel more expensive cards like upped Pandemonium or Antimatter.
Based on the polls, Kitsune will probably be sent back to a random spot in the deck. I will change that when i have time.
EDIT: Changes made and submitted to Crucible.
