I know there are all kinds of Prerelease Primers out there. We do financial ones on this site, the mothership does a larger one, there are competitive set reviews all over.
But I wanted to highlight a particular one posted to Reddit by user Torakaa today. The reason I want to share it is because it's a fairly short, simplistic but still very helpful guide. If you're a new player heading to a prerelease this weekend, this is definitely something worth checking out first.
So, the Prerelease for the Magic 2015 Core Set is next weekend. Are you interested in picking up Magic, your friends are nagging you to go, want to return to Magic after a hiatus, or any other reason? Well you are in luck, for that is the event for you!
If you have any other questions not answered in this FAQ, feel free to ask.
What is the Prerelease?
It is a casual event made to cater to newer players. It is open to all players even if you have barely played Magic before. The atmosphere is made to be relaxed and players are encouraged (and often willing) to help out newer players. You can use the Wizards Store Locator to find a store near you. You will want to look for "Magic Prerelease - M15" in the store's event list. Make sure to get an idea of where and when the event will be; It never hurts to be a bit early. Obviously, if any of your friends play Magic, ask them where to go.
