Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When a Spell/Trap Card, or monster effect, is activated: Reveal 1 Counter Trap in your hand, then discard 1 card and pay 1000 LP; negate the activation, and if you do, shuffle that card into the Deck. Then, you can Special Summon 1 "Parshath" monster from your Deck or Extra Deck.
