So I'm fairly new to Magic (not card games, just the Magic series) and I've never been to or watched a tournament. I have decided that I want to go to the Innastrad Prerelease and I am a little bit nervous. I don't know how to build a good deck from a sealed pack or even how to act towards other people there. Does anyone have any advice for me at all in any way? Whether its a suggestion on dealing with deck building, or behaviour, or anything else. Please if you have any advice, suggestions or opinions please don't hesitate to let me know. I really hope to have fun there and it would really help me feel more at ease with this all.
