Theory about Time Cataclysm and the final expansion.

Something that's bugged me about Time Cataclysm is all the key words on the various cards in it that simply aren't used... They're not used by the deck, and they're not used by other decks (Heroes or Villains). They clearly reference other environment decks, but why bother giving them the key words when you never have more than one environment at a time?

Then, I got an idea... We know that the final expansion is supposed to have something that changes the way it play compared to other expansions. What if it involves using multiple environment decks somehow? Then if you're using Time Cataclysm and one (or more!) of the enviroments it refrences, cards which have those key words shared would be effected by the deck that inspired said card.

Sorry for the doulbe post bump, but I just wanted to say: Called it.

Although we don't know for sure that those enviroments will be allowed to interact at all.
