A conditional effect, written in the format “[EFFECT] while [CONDITION],” is an effect that only applies as long as CONDITION is met. The CONDITION is evaluated at all times while the effect exists. If the effect applies to one or more subjects, CONDITION is evaluated per subject.
Example: Parable of Humility has the text “Attack action cards your opponents control get -1{p} while attacking and defending,” which is a conditional static-continuous effect that applies to more than one object and a condition that is checked per object that it applies to.
