Magic the Gathering is celebrating its release Tenth edition by having Game Day July 14th. Participants can play Magic with the new core set and get cool prizes.
I haven't played Magic in a while but enjoy when the core sets come out. They are bigger sets than the expansions and usually have cards from past sets. It's a great way to pick up favorite cards with new artwork.
Wizards of the Coast is really promoing 10th edition. Each week at Magicthegathering.com they've been showcasing the artwork for the cards then the next week they reveal the name of the cards.
It looks to be a promising set.
