Card Text and Target
Keep the read literal. The card is accurate already. The mistake is usually the player pretending the text means room-wide Doom or pretending the card counts itself.
Base
Oblivion
Upgrade
Oblivion+
Marked enemy
The chosen target is Any Enemy, not the full room.
Trigger window
The mark watches cards played after Oblivion resolves, which is why the card does not count itself.
Turn cleanup
The mark is temporary and clears at the end of the player turn.
