Something based on this could be nice: http://elementswiki.co.cc/decks/dracoxs-unstable-air/Not saying that's perfect, and a picture would be a requirement (or at least it should be imo), but it looks to me to be a good start (overview, deck, basic strategy, weaknesses, summary).
Right, but I don't think such a deck should be allowed. Unstable gas deck might be the page, but we don't need a page for every single deck like it. A variations section, with links to the forum threads, would be much better.
Right there we have a deck called "dracoxs unstable air". Next we'll have "blah blah's unstable gas deck" and then we'll have "Puppychow's unstable eagle's deck", and before you know it there are like five unstable gas decks all on the wiki. Instead, there should be one "unstable deck" thread, with perhaps some links to specific examples.
