Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
● While in Attack Position: Once per turn, you can Tribute 1 "Morphtronic" monster, except "Morphtronic Slingen", to destroy 1 card on the field. ● While in Defense Position: If this card would be destroyed, you can destroy another "Morphtronic" monster you control instead.
--D・パッチン
--Morphtronic Slingen
