For anyone curious, the contents of the Helvaults that will be at the Avacyn Restored prerelease has been spoiled by some jackass who was then stupid enough to put things on ebay and will never be able to sell WotC products again. I don't know how much the Magic players here follow rumour season, but I figured I'd share the contents with anyone who was curious. It was known that there were 3 different things inside the Helvault, and everyone would each get one of the first two and two of the third. The way they hyped this thing, they made it sound like the three things in the Helvault were Black Lotuses, strippers, and that puppy that ran away when you were seven. If you can't wait until the prerelease and want to know, here is what is actually inside:
Black Avacyn Restored spindown D20s. (This might be what you get 2 of)
Angel/Demon double faced tokens (These are sealed in packs of 4. It is unknown so far, but each player may get their own pack of 4. This is less likely what you might get 2 of).
Oversized promos of Griselbrand and the 4 mythic legendary angels (These are sealed in packs of 5, obviously. Because the Helvault is optimized for 54 people, this is what leads us to believe you may each get a full pack of these and the tokens, as 5 obviously doesn't go into 54 evenly. Also, these oversized promos are NOT foil).
So there's cool things, but there isn't a single tournament playable card in the Helvault, which has left pretty much the entire Magic community pissed off after the ridiculous amount of hype and secrecy surrounding this thing.
