"Dice: The cube that changes everything" and "MLP" crossover where Trixie comes across the dices that let you change your lot in life.
"Congratulations on becoming a Dicer!"
This story is set shortly after the episode "Boast Busters". And I will be taking liberties with changing how the dice work to better suit the story and Equestria. This will also be set in baseline Equestria, meaning I will be trying to keep everything as close to the show unless affected by the appearance of the dice.
