Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "Meklord" monster you control; your opponent takes no battle damage from attacks involving that face-up monster until the end of this turn, also its ATK becomes (permanently) the combined original ATK of all "Meklord" monsters you currently control. If a "Meklord" monster(s) you control would be destroyed by battle or card effect, you can banish this card from your GY instead. You can only activate 1 "Meklord Deflection" per turn.
