Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During either player's turn: You can Special Summon 1 of your "Kashtira" monsters that is banished or in your hand. If your opponent activates a Trap Card or effect, you control a "Kashtira" monster, and this card is already face-up in your Spell & Trap Zone: You can look at your opponent's hand, and if you do, banish 1 card from it face-down. You can only use each effect of "Kashtira Preparations" once per turn.
