Chaos Sealed is a variant of Sealed Deck; the Chaos element comes in when you choose the product used to build your deck. Each Magic set is assigned a point value, ranging from 0 for Chronicles to 5 for Tempest. You have 15 points to use, and must choose exactly 5 booster "sets". (A set is one 15- or 12-card booster, or two 8-card boosters.)

Land is a precious resource; you only get 5 of each basic land (four regular, one snow-covered).

Chaos Sealed is typically played for ante; having limited land makes the ante loss of a land from your primary color a truly devastating blow. During deckbuilding, you may find yourself agonizing over difficult choices - like whether to save that game-breaking rare you need for your collection, or play it and risk losing it.

Like other limited formats, you build a deck of at least 40 cards. Unlike typical sealed deck, you can't add as much land as you want - just the 5 of each that you began with, plus any you were lucky enough to open.

If you don't spend all 15 points on your boosters, you can get extra basic land (1 point each).

Sound interesting? Sound like fun? (It is!) Simple, too.

And just maybe, the best Magic format of all!




Notes on latest changes:
December 2010
Eventide dropped to 4½, Tempest continues to slide, now down to 3½.
November 2010
Worldwake forgotten in earlier revisions; Prophecy underperforms, drops to 1 from 1½; added Scars.
April 2010
Rise begins and stays at 4½, a bunch more reductions in older sets.
November 2009
Reborn stabilizes at 6, Zendikar enters and establishes itself at 3.
July 2009
Onslaught and Odyssey finally seemed to live up (down?) to their value at the new, lower cost.
June 2009
Just continuing to devalue older sets, and recognizing that Reborn is really good since mana fixing is now plentiful. Also noting that basic land is of little concern now, since 5-color is common (see note re: mana fixing), and newer sets include basics anyway. This devalued extra lands and older sets that included land.
April 2009
The morphs in Onslaught are just overcosted compared to Future Sight and Future Sight is not a problem at 3. Alliances' creatures are just obsolescent and the set is only 12 cards. It contributes much like Homelands, but it certainly is not a 0. Tests only used Mirage, but it compared unfavorably to Odyssey, and the Mirage block is fairly balanced across all three sets. Coldsnap's new value is, admittedly, an experiment — but it's in line with the recent trend of ever-increasing power.
