Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can Special Summon this card (from your hand) by sending 3 face-up "Fire Formation" Spell/Trap Cards you control to the Graveyard. When this card is Normal or Special Summoned: You can Set 1 "Fire Formation" Trap Card directly from your Deck. You can only use this effect of "Brotherhood of the Fire Fist - Swallow" once per turn. Face-up Beast-Warrior-Type monsters you control cannot be targeted by your opponent's card effects.
