The original idea was for Magic in a format known as Dandan, or "Forgetful Fish". The idea was to have a shared deck and play mono blue control.

In this deck, your goal is to either kill your opponent or get to 20 mana. Sounds easy enough, right? Well, with a shared deck and deck list, limited access to certain cards, and you both playing Avatar of Water, it may be more difficult than you might think.......
