A multiverse format
Commander, or EDH, is a malleable Magic The Gathering format that is played in many different ways. By focusing on the social aspect of the game it has opened up many ways to enjoy Magic. Unlike conventional formats that are mainly played at their competitive edge, EDH facilitates games at all levels of play: from cEDH to all possible kinds of casual Commander. This diversity is great in that there's something in EDH for everyone. And everyone should be able to find an EDH game they will enjoy. Regardless of budget, skill or time.
At the same time this open-ended nature of the format has led to many different preferences and ideologies among the EDH player base. So different that sometimes it can seem as if the person accross the table is playing an entirely different format. In that sense EDH has become somewhat of a format multiverse in which several diverging interpretations exist at the same time. And not all of them are going to be compatible with each other. Aligning expectations during a pre-game talk is advised to increase the odds of an enjoyable time, especially when playing with strangers, but that can be easier said than done for many. "The EDH Multiverse" guides are tools aimed at helping players in this process. They are power level guides that focus on the gameplay experience rather than numbers and that you don't have to show to other players for them to work.
Trying to win and trying to prevent others from winning are two fundamental drivers in the game. In EDH, the extent to which these two drivers are pursued will lead to different experiences that different players prefer. "The EDH Multiverse" guides use those drivers to describe how expectations about EDH can differ and how they can impact gameplay. The chart paints a picture of the EDH landscape and gives pointers on how you can navigate its many interpretations. Like assessing for what type(s) of EDH your deck(s) might be suitable, what you can do to increase the format coverage of your deck suite, how you can express what kind(s) of EDH you prefer, what questions you can ask and answer to gauge expectations, and what you can do to get in the same ballpark.
