Fantasy Fluxx

From BoardGameGeek:

Fluxx is a card game in which the cards themselves determine the current rules of the game. By playing cards, you change numerous aspects of the game: how to draw cards, how to play cards, and even how to win. At the start of the game, each player holds three cards and on a turn a player draws one card, then plays one card. By playing cards, you can put new rules into play that change numerous aspects of the game: how many cards to draw or play, how many cards you can hold in hand or keep on the table in front of you, and (most importantly) how to win the game. In Fantasy Fluxx, you want to gather your friends for a party - an adventuring party, that is! Pack up your Second Breakfasts, and set off on a classic quest with your faithful companions: the Helpful Elf, the Dwarven Warrior, the Gallant Swordsman, the Wise Old Wizard, and of course, the Humble Young Hero! Learn from the Cranky Magic Teacher how to use your Wand to cast spells like Invisibility or Fireball! You may need them as you encounter the Dreaded Pirate, or when you find out that Captured Princess is actually the Mother of Dragons! Will you and your fantasy favorites survive the Final Showdown with the Dark Lord?
