Special Summon this card as an Effect Monster (Rock-Type/LIGHT/Level 4/ATK 1000/DEF 1800). (This card is also still a Trap Card.) While this card is an Effect Monster, if another Trap Card you control that is 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 in the Spell & Trap Card Zone instead.
Special summons 2 trap cards from your deck and sets them as monsters. After a space in your monster zone is freed up, activate Tiki Soul. Then any other trap card in your monster zone, destroyed by your opponent, will be set to your spell/trap zone.
Continuous trap monsters
Tiki Soul allows you to reuse continuous trap monsters as long as he is face-up. Building a deck full of these monsters helps you maximize the effect of Tiki Soul.
