Range is a parameter that describes the number of cards or variables affected by a command.

Acceptable forms:

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.
