An identity-replacement effect is a replacement effect. Identity-replacement effects are typically written in the format “As [CONDITION] [MODIFICATION],” or “[CONDITION] (as/with) [MODIFICATION],” where CONDITION describes an event, typically an object entering the arena, and MODIFICATION describes the modifications to the event.
Example: Hyper Driver has the text “This enters the arena with 3 steam counters.” This is an identity-replacement effect where the condition is the Hyper Driver entering the arena and the modification is that it enters the arena with 3 steam counters on it.
