Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn: You can equip 1 "Inzektor" monster from your hand or GY to this card. While this card is equipped to a monster, that monster's Level is increased by 4. While this card is equipped to a monster: You can send this Equip Card to the GY; the monster it was equipped to can attack directly this turn. Other monsters cannot attack the turn you activate this effect.
