Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Plant monsters This card cannot be targeted for attacks, but does not prevent your opponent from attacking you directly. You can Tribute 1 monster, then target 2 Plant Link Monsters in your GY, except "Sunavalon Daphne"; return them to the Extra Deck. You can only use this effect of "Sunavalon Daphne" once per turn.
