The Zet, Lightning Sonic/Rulings


 * Q: My The Zet, Lightning Sonic attacks and then uses an Invasion ability, putting a creature such as Redzone, Roaring Invasion onto it. Do I need to destroy it at the end of my turn?
 * A: While The Zet's ability triggers if it had attacked, the ability triggers at the end of your turn. By then, your creature is already a different evolution creature. As The Zet is not treated as being in the battle zone at the end of your turn (as any effects from a under an evolution creature while it's in the battle zone is ignored.), its ability that would destroy itself doesn't trigger so no creature needs to be destroyed.
