Question

Is the ability on Get Behind Me! (Core Set #78) a replacement effect? It doesn’t conform to the “when [triggering condition] would happen, do [replacement effect] instead” format described in the RRG, though it does use the “instead”, and the attack effect on does not replace the trigger condition, rather the villain attacks in place of the cancelled When Revealed ability. Can a cancelled ability even be replaced? Or is the use “instead” sufficient to make it a replacement effect?
