The elusive card turned out to be a common no one was reporting on.
Mischief of the Gnomes
Normal Trap Card
This turn, reduce the Levels of all monsters in each player’s hand by 1 (even after they are Summoned/Set). You can banish this card from the Graveyard; this turn, reduce the Levels of all monsters in each player’s hand by (1?) (even if they are Summoned/Set).
Also, Double Trap Hope seems to remain as a shortprint Common, as expected.
