Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Tuner + 1+ non-Tuner monsters When this card is Synchro Summoned: You can destroy all cards on the field. Once per turn: You can banish 1 Plant monster from your GY, then target 1 Defense Position monster your opponent controls; change that target to face-up Attack Position, and if you do, its ATK becomes 0 until the end of this turn.
