Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Level 4 "Fire Fist" monsters You can detach 2 materials from this card, then target 2 "Fire Fist" / "Fire Formation" cards in your GY and/or face-up field, and 2 cards in your opponent's GY and/or face-up field; shuffle those targets into the Deck. You can only use this effect of "Brotherhood of the Fire Fist - Cardinal" once per turn.
