Since I don't feel like writing about sealed deck (all I would do is ramble on about how it is even more luck based then constructed, and give countless stories of repeated Torchings, and Fireballings, and Armor-Beat Downs) here are some links to some interesting stuff from Frank K's Magic Dojo pages ...
In general I feel that 'Big Money' events like pro-tours and world championships should not be decided by somebody getting a Savage Twister, Kaerveck's Torch and Ray of Command in his/her packs ... then 'Skillfully' deciding to play with them. It's just plain lame ... If it's part of an event say , 4 out of 10 rounds ... I could live with that , but otherwise I see it as too luck intensive.
