I know this is somewhere between very unlikely to never happening, but it would be cool to see your mark in game get "distorted" based on the deck make up you are currntly playing.
For example, if you were using a Life mark, but had entropy in your deck, your mark would look like the inverted Life mark at the beginning of this thread. The more different elements you have in your deck, the more distorted the mark would become.
Like I said, doubtful, but fun to speculate on
