Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
FLIP: Target 1 face-up monster on the field, and if you control a Warrior monster, you can target 1 additional face-up monster on the field; place the first target on top of the Deck, then return the additional target (if any) to the hand if you still control a Warrior monster.
