Having read through that interesting debate between ScaredGirl and cipher_nemo, it seemed very plausible, as described in that thread, to in fact incorporate multi-casting cards in the game. Most of the discussion on the above linked threads (with one leading into the other) was about rainbow's power and that this is not MtG (which I think we all can easily agree on).
I did run into another interesting point in this conversation that I have yet been unable to pursue. What and where is the official Elements storyline? I've read a few player suggested ones, both here and Kong, but I can't seem to track one down on this forum. On the wiki, this is all I've been able to find, short of the opening paragraph on intro to basics and the one-liners for each element:
http://elementsthegame.wikia.com/wiki/Fan_Based_StorylineI assume since it's a fan-based story it's not official, but even if it was, it doesn't explain how we, the individual players, develop, control, maintain, or otherwise manipulate or become the elements. Why do we use pillars? How can we use other elements that aren't ours, ex- Fractal Pest: Aether/Dark- Am I able to channel Aether being a Darkness elemental or vice versa?
I don't mean to nitpick and I am not trying to be difficult. If my suggestion doesn't fall within the established storyline, point me to it, I'll take the time to read it and forfeit my suggestion should it be clear it doesn't fit. But if there is no defined storyline, please don't use the storyline argument to shoot down suggestions. I've mod'ed/admin'ed on RP servers in the past where I've written/read hundreds of pages of storyline related ideas in an effort to maintain and keep a healthy storyline active and moving forward and I know what it takes to make it all work. But if the storyline is not somewhat fluid to allow the multitude of individual ideas and suggestions to keep it relative, the storyline will become stagnant, potentially killing ideas before they even come to light. However, not to sound harsh, the storyline on a game like this is mainly for flavor, with the side benefit of generating ideas for cards. I have to believe that the majority of Elements players pay very little attention to any storyline and only log in to play a really cool card game.
If there is a storyline, even though it may not be extremely relevant to the masses, an easier way to find and read it should be made available. I have tried for a couple of hours to find one and have been unsuccessful. If it does exist, it is buried deep within the community of Elements.
That all said, barring a storyline, the original question still seems valid. Would incorporating multi-casting cards be something Elements might be willing to do?
On a side note, I have had the pleasure of writing many a story in my day (is old fart) and it might be fun to refine some of the posted storylines into one consistent and accepted story, barring approval from the Elements community. This is assuming there is no established story. If there is, disregard this offer and I look forward to reading it!
