Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card you control is destroyed by your opponent's card (either by battle or by card effect) and sent to your Graveyard: You can excavate the top card of your Deck, and if it is a Plant-Type monster, send it to the Graveyard. Otherwise, place it on the bottom of your Deck. If this card is excavated from the Deck and sent to the Graveyard by a card effect: All Plant-Type monsters you currently control gain 300 ATK and DEF.
