Sideboard Dice

Button Notation:	Left hand side with darker frame
BMO Notation:	rS (not implemented)

Sideboard dice are dice set aside at the beginning of a match. A Sideboard Die may be swapped for an Active Die whenever a round is lost. The Sideboard Die becomes an Active Die, and the Active Die becomes a Sideboard die.

The Sideboard Die was used in the High School Drama set.

On the Button Men Online site, Sideboard Dice are to be implemented as Reserve Select Dice, with all High School Drama characters having five Select Dice at the beginning of the match.
