Elemental

Players: 2-3

Elemental is a card game with a rock-paper-scissors system of win-lose conditions.

Each card has an Element symbol on it. The elements are Water, Fire, Earth, Wind, and Magic.

Water beats Fire and Earth.

Fire beats Wind and Magic.

Earth beats Fire and Wind.

Magic beats Earth and Water.

Wind beats Magic and Water.

Each player draws 5 cards. At the beginning of a round, every player has 10 health points. The first player must pick a player to challenge, and an element card to challenge with. He must then display that card. 

The challenged player may now play an element card which defeats that one, if he has one. 

Then, the original challenger may play one more card that defeats his opponent's element, if he has one.

Finally, if there is a third player, he may choose to defend the challenged player with one of his cards. If this is the case, the challenger loses one health point. If the challenger wins, his opponent loses one health point.

If a player loses all health points, they are knocked out.

The round continues until only one player remains.
