Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
At the start of your Main Phase 1: Banish 3 or 6 random face-down cards from your Extra Deck, face-down; draw 1 card for every 3 cards banished. For the rest of this turn after this card resolves, you cannot draw any cards by card effects.
