Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Plant monsters If this card is Link Summoned: You can choose a number from 1 to 3 and excavate that many cards from the top of your Deck, and if you do, you can Special Summon up to 2 excavated Plant monsters, but they cannot be used as Link Material, also send the remaining cards to the GY. You can target 1 Plant monster in your GY that has a Level; the Levels of monsters this card points to become that monster's Level, until the end of this turn. You can only use each effect of "Sylvan Dancepione" once per turn.
