Range is a parameter that describes the number of cards or variables affected by a command.
Range:1 ---Can also be any other arbitrary number. Choose 1 Card/Variable.
Range:3UPTO5 ---Choose 3 to 5 cards/variables.
Range:3UPTOINF --Choose 3 to Infinity cards/variables.
Range:All ---Choose all cards/variables.
Style Tip: Instead of saying something like Range:0UPTO3 , where one had the choice to choose 0 cards, it is better to make the effect Optional and change it to Range:1TO3, to make it less confusing for the user.
