Number of Players: 3 - 10

Number each player, then have a die with at least twice that many
sides. At the beginning of each turn, the active player rolls the die.
If the number rolled corresponds to a player, the active player cannot
attack or target the rolled player this turn. If the active player
rolled their own number or a number that doesn’t have a player, they
can target anyone but all of active player's creatures must attack
this turn if able instead.
