Sanctuary of the King's Treasures

You can only use this Skill's second and third effects once per Duel if your Deck contains a total of 15 or more Trap Cards.
1: At the beginning of your first turn, place 1 "Temple of the Kings" from outside your Deck face-up on your field. You cannot activate the effect of "Temple of the Kings" on your first turn.
2: If you control a Continuous Trap Card, send 1 card from your hand to the Graveyard, return any number of Continuous Spell Cards and/or Continuous Trap Cards to your hand. Then, Set 2 Continuous Trap Cards from your Deck that can Special Summon themselves as monsters. (These cards can be activated the same turn.)
3: From turn 2 onward, add 1 Level 10 monster from your Deck or 1 "Mystical Beast of Serket" from outside your Deck to your hand.
