Purge
From Archon Arcana - The KeyForge Wiki
When a card is purged, it is removed from the game and placed faceup beneath its owner’s Archon identity card. Purged cards are out of play and no longer interact with the game state.

Commentary
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.
