Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When a face-up "Karakuri" monster you control selects an opponent's face-up monster as an attack target, you can change the target's battle position. When this face-up card on the field is destroyed and sent to the Graveyard, you can select 1 Level 4 or higher "Karakuri" monster in your Graveyard, and Special Summon it.
