Tiki Soul (GLD5-EN054) [Gold Series: Haunted Mine]

After activation, Special Summon this card; it is treated as an Effect Monster Card (Rock-Type/LIGHT/Level 4/ATK 1000/DEF 1800). (This card is still treated as a Trap Card.) While this card is treated as an Effect Monster, if another Trap Card you control that is treated as a monster would be destroyed by your opponent's card (either by battle or by card effect) and sent to your Graveyard, you can Set it on the Spell & Trap Card Zone instead.
