REDU format ruling
Question

Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)When activating this card, your opponent cannot check cards in the Graveyard. Your opponent calls the name of the first monster found at the bottom of your Graveyard. If he/she calls it right, the monster is removed from play. If he/she calls it wrong, the monster is Special Summoned to your side of the field.
Rulings
- Remember that you cannot shuffle your GY or change the order of cards in your GY at any time.
- If a monster is named with Question that could not be Special Summoned, Question’s effect disappears and the monster is neither Special Summoned nor removed from play. So the effect of Question disappears if the bottom monster is incorrectly named and is Helpoemer, Dark Ruler Ha Des, etc.
- If you would Special Summon Tyrant Dragon from the GY using Question, you must Tribute 1 Dragon and if you cannot you cannot Special Summon Tyrant Dragon and the effect of Question disappears.
