I dont like this idea.
Firstly, elements is a great game becoz it is elements, not another card game. So why we have to rename the game and change the style (creature blocking)? Pillars are not lands and lands are not pillars.
Secondly, ledendary card is NOT a good idea. Becoz you dun have money for it? Nope. Zanz said it would be very powerful and very rare. Battles will become very luck based, i can imagine first-draw-first-win happening in the future. RARE cards are nice, but not OP cards. I have a feeling that the developers in the future are just selling OP cards for money.
Thirdly, it is about the monthly fee. Yes, the game needs money. But will people pay for a game after seeing some comments from it without playing it? I am afraid not much will give a try to this game.
Lastly, I dont like the idea of 13th element. 12 is a good number, and after seeing the description of 13th element i can imagine that it would become the most popular and powerful one. If you want more cards, why not stay with the existing 12? I fear this is due to commercial reasons too.
I dont know if i will continue playing this game. The money is not my consideration, I think the game will become no longer entertaining in the future (mainly due to 2nd reason)
