Instruction: Elements is a fantasy card game online. 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.

Each elemental receives 100 health points (HP) at the beginning of the match, the duel is over when one of the elementals reaches 0 HP or runs out of cards. There are 3 types of cards:
-Creature cards: These cards will summon a creature that will fight for the elemental; creatures have a certain amount of attack power, health point and special skill themselves.
-Spell cards: Spells have an immediate outcome; spell cards are discarded after their effect took place.
-Permanent cards: Permanents are artifacts, equipment, or any other item that will remain in play for an indefinite amount of time.
