What Have I Done

If you would flip a coin, you may pay {1}. If you do, instead choose the result of that coin flip.
At the beginning of your upkeep, put a volatile counter on What Have I Done. Then, flip a coin for each volatile counter on What Have I Done.
Whenever you lose a coin flip, you lose the game.
