Both players must show their hands to the opponent when "Royal Tribute" resolves.
This card can only be activated when Necrovalley is on your side of the field. Both players discard all Monster Cards in their hands to the GY.
If you activate "Royal Tribute" and your opponent chains "Mystical Space Typhoon" to destroy "Necrovalley", the effect of "Royal Tribute" still resolves.
Necrovalley only needs to be face-up on the field when this card is activated.
This effect resolves successfully even if Necrovalley leaves the field in the Chain.
