Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Discard 1 card, then target 1 "Vendread" monster and 1 Ritual Spell in your GY; Special Summon that monster in Defense Position, and if you do, add that Ritual Spell to your hand. You can banish this card from your GY, then target 5 of your banished Zombie monsters; shuffle them into your Deck, then draw 1 card. You can only use each effect of "Vendread Revolution" once per turn.
