An activated-layer is a layer created by an activated ability. An activated-layer is created on the stack, and then can only exist on the stack.[5.2]
Example: Energy Potion has the text “Instant – Destroy this: Gain {r}{r},” which is an activated ability. When this ability is activated, it creates an activated-layer on the stack with the resolution ability “Gain {r}{r}.”
