While the Tournament Judge is alive on the field, you get to see what your opponent's left most card is. The way I picture it functioning in game is that card would be flipped in your opponent's hand and you could mouse over it for a full viewing. If the Judge dies however, that card become hidden again and obviously, once that card had been played, you will no longer have any idea what card you may take in exchange for your right most card (Though you would still have access to Change the Rules).
Change the Rules is pretty self explanatory. When you feel the time is right, you can swap the right most card in your hand (ie: the card you most recently drew/added) for the left most card in your opponent's (ie: A card they've been holding on to). The implications should be apparent. This can break up combos, rob your opponent of powerful cards and just overall disrupt your opponent's game plan.
As a note, Change the Rules would only function so long as you and your opponent had cards to swap. IE: If you played Change the Rules while it was the only card in your hand, the card would do nothing. You would not be able to take a card from your opponent without giving one in return and vice-versa.

The idea for flavour of the quest is that you're experimenting on your minions until you finally uncover the key to Alchemy. Philosopher's Stone could be used to set up combos (eg Doomguard, Malygos) or just overwhelming value (Lich King, Voidlord). Board clears such as Defile or Hellfire killing your minions would count and be an 'easy' way to advance the quest, albeit it at a tempo and card advantage cost. Other synergies lie in cards like Dark Pact, Shadowflame or Unwilling Sacrifice.
I want a fancy title, but I'm neither as godlike as our lord and savior Fluxflashor, intelligent as ShadowsOfSense, as helpful as Linkblade91, as hardworking as ThisOtherGuyTox, or as inactive as Otovent.
"Sharing positions" is pretty straightforward: if you and your opponent both have minions in the second and third spot of your hand, all four minions would be summoned. The card can function well in a Big or Quest Priest to drop heavy targets (
The Lich King
, etc.), or it can be used as a mass-
play for disrupting comboes/purging your opponent of threats. Preferably, you would achieve both of those at the same time ^_^
