Usage

For interfaces, implement them in your card class. For fields, set their values in the constructor of the card. The specifics may vary slightly.

For example, to give a card Exhaustive 2 you would do ExhaustiveVariable.setBaseValue(this, 2);. For those that are true or false, it will be more along the lines of PurgeField.purge.set(this, true);

All keywords should use the stslib: prefix in card text. Effects with numeric values also come with their own dynamic variables to use in card text. For Exhaustive, it would be stslib:Exhaustive !stslib:ex!.
