Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control no monsters, or only control "Queen's Knight", "King's Knight", and/or "Jack's Knight": You can Special Summon 1 "Queen's Knight", "King's Knight", or "Jack's Knight" from your hand or GY. You can banish up to 1 each "Queen's Knight", "King's Knight", and/or "Jack's Knight" from your hand and/or GY; draw the same number of cards you banished. You can only use 1 "Court of Cards" effect per turn, and only once that turn.
