Rulings
- If you Special Summon Guardian Tryce, you don't get to activate his effect when he's destroyed, even if you Tribute Summoned him previously and are using Monster Reborn on him later.
- You must Special Summon the exact same card that was Tributed for Guardian Tryce when using his effect; you cannot Special Summon a card of the same name.
- You cannot use Guardian Tryce's effect to Special Summon a Special Summon-only monster that had not been properly Summoned, such as a Fusion Monster that was Special Summoned with Magical Scientist and then Tributed for Guardian Tryce.
- You cannot Special Summon Dark Ruler Ha Des with Guardian Tryce's effect.
- You can Special Summon a monster in your opponent's GY if it was used to Tribute Summon Guardian Tryce.
- If Guardian Tryce is an Equip Spell Card equipped to Relinquished or Sword Hunter, and Guardian Tryce is destroyed and sent to the GY, his effect activates.
- If Guardian Tryce is Set and is destroyed, his effect activates.
- Q: If Player B uses "Change of Heart" on Player A’s monster and Tributes it for "Guardian Tryce", when "Guardian Tryce" is destroyed, does Player A’s monster get Special Summoned to Player B’s field? A: Yes. bishop 02/23/04
- Q: If I use "Soul Exchange" one of my opponent's monsters for the tribute, and "Guardian Tryce" is destroyed, would I get to special summon the opponent's monster on my side of the field? A: If that exact monster used for the Tribute Summon of "Guardian Tryce" is still in the opponent's GYthen you would be able to Special Summon that monster per "Guardian Tryce's" effect. Note: You could not do this if the tributed monster was "Dark Ruler Ha Des" or was a monster that had Special Summon requirements that would prevent it from being Special Summoned.
