Though I’ve only been playing EDH for a few years now, I’ve known about the format since 1996, when an article titled Elder Dragon Legend Wars (click here to see the text of the article) was posted in The Duelist magazine.
Back in my day, the format was called ‘Elder Dragon Highlander’, since building around one of the Elder Dragons as your general was the original premise. Even though EDH has evolved past that, with players being able to choose any legend as a general, and with Wizards of the Coast stepping in and changing the name to ‘Commander’, I will always think of the format as Elder Dragon Highlander.
Since I am still alive, it is still my day. Thus, EDH it is.
