Part of the attraction to the format it is the ease of portability. A Cubelet fits inside one deck box that can easily slide into a bag. Set up and clean up is extremely easy. You do not have to worry about having extra lands on hand. There is no draft component, but it plays very similar to a deck you would draft in a cube. You just set up and go.
Another piece of attraction is the decision tree that develops over the course of the game. Decisions you make throughout the entirety of the game influence the game itself. You choose if you want to hit your land drops. You choose what is removed from that game to become a land. These decisions reward players who can think about the long term while dealing with what is happening at that moment. For skilled Magic players, there are lots of mini tests along the way. For beginning players, there is a lot of flexibility, so you get to play the game for what it is.
Lastly, many of the aches and pains of the other formats. You never get mana screwed or flooded. There is always an opportunity to play something. You get to play the cards you love and avoid ones that you hate. In a lot of ways, it is the game at its purest form.
Start at 16:30, unless you like watching old packs get opened.
