I remember I had a game on an old phone (I'm not sure what model it was), where you played with 5 different types of energies used to play cards - 4 of them were fire, earth, water and air, and the fifth one was of your chosing (from among things like death, life, worship, mechanical etc). When you were making a deck (deck consisted of some number (6?) of cards for each element, where each basic element had 12 cards of different costs to choose from, while the 'extra' element had less (9?). The goal of a game was to lower enemy health to 0, you could play 1 card a turn, many of them were creatures played on board, which then were attacking creatures opposite to them before going for enemy hero, but some of the cards were spells with different effects.
