Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Beast monsters If this card is Fusion Summoned or flipped face-up: You can Special Summon 1 Flip monster from your hand or Deck in face-down Defense Position. If this card is in your GY: You can banish 2 Flip monsters from your face-up field and/or GY; Special Summon this card in face-down Defense Position, but banish it when it leaves the field. You can only use each effect of "Master of Ham" once per turn.
