I seem to have a complete misunderstanding of how mutations work. I am talking of the strange creatures we may get from mutation, or what you always get from improved mutations and fallen druids.
I always thought that the game pulled a random creature graphic and added a random amount to its stats, then gave it a random ability with the creature's type of quanta, and made it cost 1 or 2. However, I have found that some things happen FAR more commonly than others. For example:
Sparks have Deja Vu a lot
Firefly Queens have mutations and devours a lot
Colossal Dragons get destroy often
Fate Eggs get burrow often (this tends to stink, especially if it still has 0 attack)
Phase Dragons with Lycanthropy are common
Shriekers with Dive are common
Am I just completely crazy and imagining this, or has anyone else noticed it? I've played a deck for a while now that mutates things a lot, but this still seems irrational to me...perhaps the game is coded not to spawn random mutations at all, but certain set ones...I'm not sure.
