If I use Universal Recycle Bin (WC 179) to archive a creature that was purged by Spangler Box (COTA 132), then play that archived card, then the archived card gets destroyed, and then somehow destroy Spangler Box, does the creature go back into play?
No. When a card purged by Spangler Box is moved to your archives, any pending effects that would interact with that card (such as returning to play) will no longer resolve.
