Elements is one of the best fantasy collectible card games (CCG). The player is an elemental, a spirit composed of an element; elements are the fundamental building blocks of nature. Each elemental has an arsenal of skills that can be used in a duel against another elemental; each skill corresponds to a card. The player can pick which and how many cards to use in the duel and collect them together in a card deck.
