The pre-releases for Conflux will be a lot more fun than Shards.
Drafting, Open Dueling and 2-Headed Giant are now approved at all pre-
releases. I know for sure the Convention Center will have a morning
and afternoon 2-Headed Giant, but I don't know the stores' schedules
(I added their phone numbers at the end of this email).

Also, the pre-release at the Convention Center will be
one of the Regional Preleases and will have the artist Mike
Dringenberg drawing, signing autographs and possibly selling artwork
and artist proof cards.
