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.
This thing can combo with Magical Hats. Use Magical Hats on Tiki Soul and the Traps that you select that get destroyed as monsters get Set due to triggering Tiki's effect. Only works if your opponent attacks though.
