T2 Sealed was a pretty good success this past weekend at the T2 only though we did learn a couple things.
First of all, being that you are only allowed 1 single-color Site in regular Sealed, we probably should have realized that there should only be 2 single-color Sites in T2 Sealed. I'm sure Gabe would agree
Secondly, it does cost quite a bit. Bill is an extremely generous guy, but it would be difficult for any host to give that kind of deal on a regular basis. For that reason T2 Sealed probably won't become an official category.
Third, it was fun to see how some cards that you never (or rarely) see in regular decks become beasts in T2 sealed. The best example of this that I saw was the Abram/Abraham that Alex picked up. After making a successful rescue in one game, Alex now had Abraham and not only that, but had gotten at least 2 copies of Covenant with Abraham. Needless to say, Abraham went into Beast mode picking up LS left and right.
