I don't really keep records of EDH games, but with the advent of brawl on arena I decided to keep a record of my stats throughout the week. It was an interesting exercise to say the least, discovering how frequently I won and lost over time and particularly whether or not my win-rates evolved as I played more and memorised each of the decks and possible answers to my actions.
I realise that most individuals here will have little interest for brawl, but I felt like posting my stats here anyways, because why not.
Percent certainty for overall win % is ~4.21
