Anyone who is interested, there will be a major PvP event, which will start soon. More info can be found here: http://elementscommunity.org/forum/war/ This will be surely the swansong of the game, I'd advise you to check it out. :-)
Dmitry, grinding was much more worse back in the day. Nowadays you can get to level 60 in TWO HOURS. Other than that this game isn't really good for soloing, PvP is much more interesting. Check my 2 links below and find opponents there.
still works, check the official site http://www.elementsthegame.com/
the forums http://elementscommunity.org/forum/ and the chat elementscommunity.org/chat/blab.php
I advise you to experiment more. AI1-3 easily beatable with basic decks. Check your quanta: if you produce too much then remove some and add more creatures. Starting decks aren't good gotta adjust them. Give a bit more time to the game it does worth it.
Hey Selyob! It isn't that fun to play against AI3 / AI4, true. Try playing against human another player and you'll see the strength of this cute little game. Hint: there are no invincible decks, there is always a solution to beat that pesky deck played by your opponent! Of course, there are powerhouse decks, but the rock-paper-scissors nature of the game provides solutions. Also there are less powerful, but oh-so-satisfying-to-play combo decks as well. Ask around in chat, play with other players, read forum/wiki, try different decks against different players, and you'll love it!
Certain permanents disappear, because they have only a limited usage. Wings - 5 turns, Dimensional Shield - 3 turns, Sundial - 1 turn, Bone Wall - limited number of bones, Dissipation Shield - quanta-based.
Outlawzz: In fact you can get all cards in like 2 hours, just find the correct strategy. Click that Arena button, and marvel how quickly you can get money even with the lousiest deck. However it isn't bad sometimes to ask nicely for advice, search the forum or the wiki for decks and learn.
