While “Imperial Order” and “Talisman of Trap Sealing” are both active, and “Sealmaster Meisei” is removed from the field, “Talisman of Trap Sealing” stays on the field, but if “Imperial Order”’s effect is no longer being applied, “Talisman of Trap Sealing” is destroyed.
“Talisman of Trap Sealing” is destroyed immediately when “Sealmaster Meisei” is not on the field. If your opponent chains “Ring of Destruction” to “Talisman of Trap Sealing” to destroy “Sealmaster Meisei”, “Talisman of Trap Sealing” is immediately destroyed when “Ring of Destruction” resolves.
If you have “Talisman of Spell Sealing” and “Talisman of Trap Sealing”, the controller can select which effect will be applied. If both players have both, the turn player chooses which effect is applied.
If you have “Talisman of Trap Sealing” and “Sealmaster Meisei” is destroyed in a battle that causes you to take 2000 or more damage, you cannot activate “Nutrient Z”.
