During the Avacyn prerelease event a Helvault has been opened in each store... you can find a lot of video on youtube.
The Helvault contained :
- Avacyn D20 dice
- 54 Oversize cards (of the 5 mythic Legendary creatures from Avacyn)
- 54 double face token Angel / Demon
Each cards were given to players at the end of the event.
It's very nice to get free stuff during prerelease.
This is a regular Helvault.
But, have you heard about premium ones ?
Some stores get special Helvault, with :
- Avacyn D20 dice
- 54 Oversize cards FOIL (of the 5 mythic Legendary creatures from Avacyn)
- 54 double face token FOIL Angel / Demon
- 54 Promo cards
Some premium stores opened 54 Semonic Tutor DCI as promo cards, another store get Karmic Guide DCI.
I was in a premium store during this prerelease, so I received a foil Oversize card, a Foil Token, and a Serra Avenger Dci.
Thanks MagicBazar :)
That was a very nice surprise :
