Would like to start by saying I’m completely new to this so please be kind. Played Magic for the first time two weekends ago on a guys trip and had a blast once I figured the basics out and have been playing magic the gathering arena on my phone. I Would like to start building my own decks. My friends are very into it and I could ask them from advice but I would like to take them by surprise on our fall trip by having my own decks. Do you simply start by buying magic decks? Can you use the edition cards(like tmnt) with regular decks? Thank you all! And please remember I’m completely new, pry a lil dumb to this…so be kind!
