Sets released: Planar Chaos, Future Sight, Tenth Edition, Lorwyn

Major changes:

  - Future Sight introduced the idea of players being more like objects
  in the game.  For example, protection was extended so that it could
  be gained by a player.

  - Future Sight introduced new card types ostensibly from the future:
    - The Planeswalker type was referred to but not used.
    - The Tribal type was used - it attaches a creature type to a
    non-creature card.

  - Future Sight introduced new keyword abilities for exising
  functionality:
    - The ability reach was introduced to represent the ability of
    a creature without flying to block a creature with flying.
    - The ability deathtouch was introduced to represent the ability
    of a creature to destroy creatures that it damages non-lethally.
    - The ability shroud was introduced for permanents or players
    that can't be the target of spells or abilities.
    - The ability lifelink was introduced to cover some of the cases
    where a creature's combat damage triggers life gain.

  - Lorwyn introduced the Tribal type "properly", using it on a number
	of cards to improve the flow of the "creature type matters" theme.

	- Lorwyn introduced the changeling ability, which grants all creature
	types.

	- Lorwyn introduced actual Planeswalker cards.	These cards have
	abilities that you can play one of, once, during your main phase.
	The card has a loyalty score and comes into play with that
	many loyalty counters, and its abilities cost an increase or
	decrease of a certain number of counters.  The Planeswalker may
	be damaged by effects that would deal non-combat damage to you
	(as a redirection chosen by the effect's controller) and may be
	attacked (you assign blockers for the Planeswalker as normal).

Minor changes:

  - Planar Chaos introduced a "parallel universe" card frame.

  - Future Sight introduced a "future worlds" card frame.

  - Future Sight created a lot of combinations of ideas that had not
  been tried before, and may never be tried again, such as a land,
  an enchantment and an artifact with morph, and more general
  typecycling abilities such as slivercycling.

  - Some terms appeared on only a few cards in Future Sight: delve, 
  gravestorm, aura swap, grandeur, transfigure, fateseal, frenzy,

  - Abilities champion, hideaway and evoke appeared in Lorwyn.

  - The Kithkin and Treefolk creature types were used more in Lorwyn
	block than ever before.
