Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is activated: You can target 1 Level 5 or higher monster on the field; it gains 1000 ATK/DEF until the end of this turn. Negate any opponent's Spell effect that resolves in the same column as a "Mekk-Knight" monster you control. * The above text is unofficial and describes the card's functionality in the OCG.
