Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Gains ATK equal to its Level x 300. Unaffected by activated effects from an opponent's monster whose original Level/Rank is lower than this card's Level. Each time a "F.A." Spell/Trap Card or effect is activated: You can increase this card's Level by 1. If this card is Level 7 or higher, any card sent to your opponent's GY is banished instead.
