Rulings
1. Its cost effect counts as a re-supply cost.
2. Continuous supplies do not enter already supplied to a unit, you must pay its supply cost in order to supply it to a unit.
3. Continuous supplies – as the name would suggest – stick around when a normal supply would normally go to the grave with the unit it was attached to.
