I also agree with previous comment made by tyfwnas regarding a limit to cards in a deck, maybe promos too. I have a feeling there will be some cards in the pipeline that will be counters to the elite mainstays now like wisp, butcher and force the meta-game to shift. However, will it be in time or be successful? It is more of a competitive environment which makes for boring elite decks, but there are many creative and fun deck ideas to be put together, just maybe lacking the casual arena to do so without the mana and imperial repercussions.
How about adding a box on the selected island for "Appoint" similar to selecting an island with a Barbarian and you have "Attack" and "Ask Help" as the options, as well as selecting "Attack" at the bottom?
