From Archon Arcana - The KeyForge Wiki

When a card is purged, it is removed from the game and placed faceup beneath its owner’s identity card. Purged cards no longer interact with the game state in any manner.

Official rules v1.8 March 2021


If a card with a Destroyed: ability is directly purged, that Destroyed: ability will not resolve. For example, Oubliette is one of the few ways to cause a Bad Penny to leave play without it returning to its owner's hand.
