I've always believed Magic the card game was not exactly appealing to the masses due to it's learning curve and complexity. Herein lies the strength of Elements. It has all the fun and addictive qualities of Magic without the intimidation of a difficult ruleset to learn. The game play in Elements is faster, smoother and more intuitive while still retaining a great deal of strategy on the playing field and deck building.
Getting to my point, there are lots of free flash games on the internet. Most are garbage, many are good but only a handful are exceptional. Elements falls into the latter category. While I love the fact that Elements is free, I believe it is not getting it's due following. I would bet the farm that giving Elements exposure to other platforms, namely mobile devices and perhaps the ipad, offered for a modest fee, Elements could clean up house.
Hope I don't get slammed for this thread, but put me in the category of those who say, hire those developers. Expand the content. Charge a modest fee(while keeping the free version perhaps?) and take the chance on making a small fortune for yourselves. The card game genre right now is starving for a development like this to come along.
Good luck in whichever direction Elements takes you!
