I was going to do an article featuring some more matchups and another updated look at long, but its probably not necessary unless LED isn't restricted, which it may not be. I was going to include a KC tournament report and a suggested updated list, but I'll just do that here.
Smart people know now that chalice for 1 is better than chalice for 0. That makes Overload/Crumble Old Tech. This also increases the necessity of a good SB.

Some Comments:
Before the KC tournament, I had dome some thinking about the necessity of having a Tendrils maindeck - a decion made way back
http://www.themanadrain.com/cgi-bin....;t=9890For people who are really good with the deck, I honestly don't think the maindeck Tendrils is necessary anymore. It can win you games if you screw up - and it can win you games faster, but it won't really win you games you wouldn't have otherwise been able to win by playing a bit longer.
In other words, Tendrils is a really close crutch, but it is a crutch - but i'm too pussy to take it out. But I think for the strong willed, it should happen. Spoils of the Vault. This is a card that could come in in a few copies if you cut a few cards.
Glimmervoid. Worst Case scenario, you use it like a lotus petal to cast Xantid Swarm - and even then its very good. Glimmer void is auto-include now - in my testing I have never had to sacrifice it for lack of artifacts. I have never had any reason to doubt my own capabilities with Long - but other people have been insistent that it is terrible or whatever. I hope that LED isn't restricted so we get some more time to abuse this deck.
In the meantime, the metagame should be shifting to deal with DARGON, so that should leave some room for long to come in and clean up say, in a month or two.
The Sideboard requires alot of thought for this deck. I think this SB configuration is probably as close to optimal as you can get in a random metagame.
If LED gets restricted, the deck barely loses any steam. In very limited testing so far, 3 Elvish Spirit Guide has shown to be very robust in the three LED slots as Green Lotus Petals. I look forward to what the future brings. In the meantime - tune your other decks for DARGON or else play long

.
EDIT:
I forgot to mention this - and its an important point strategically. For a long time I harped on the importance of winning as quickly as possible. With Stifles and other cards lurking in the wings, going for the fast kill may be unadviseable as opposed to going for the secure kill.
