Today I made a platinum arena deck based on the Maxwell's Demon I had spun. It didn't do very well, going worse than 500 rank with some record like 1 win and 4 losses. I played PVP2 a few games and then went to the arena again. The arena reset and gave me the intro screen with text boxes and arrows describing what the buttons do when you click on them, as if I had entered the arena for the very first time.
It then allowed me to make a new deck based on a skeleton card. I have checked and I cannot visit the Oracle again yet. Now that I have built a new deck with the skeleton it has moved to the left circle and today's spin, the Maxwell's Demon is in the right circle informing me I can build a new deck with the same card I had spun earlier and already failed with.
